Thank you for sharing Few noticable things I would love to be clear about. 1. The temperature at which acetone and the sample is to be heated is not indicated 2. The buffer solution is also not indicated weather it is of 10pH or so . 3. And if possible I would love to understand where the 0.0313 x10⁶ is coming from and which type of oil is applicable to Thank you I will really appreciate
This was very easy to follow, but can this procedure be used for ethanol as well? Cause I'm having a really hard time finding phosphorus content determination procedures for ethanol. It'd be a great help if you could answer ❤
what is the temperature acetone need to be heated? according to a previous comment you have mentioned to 80C. bout acetone boiling point is 56C. is it okay to heat around 45C?
The reference that you have cited at the beginning of the video does not indicate where the calculation factor of 0.0313 is taken from. Is there by any chance that you could tell me how this value was derived, or give me a link to a material that can maybe make the reason clearer why this is the value for the calculation factor? Thank you very much!
was the formula that you used for phosphorus content based from the formula for percent chloridate titrated? it is the only formula from the reference book that i have found to be somewhat related, it is in page 205.
Hi what is the specific edible oil in the video and does that factor 0.0313 apply to all kinds of oil as in can I use it for sunflower soyabean or any other oil
It would be beneficial to share the Calcium Test of Limestone Grid and Calcium and Phosphorus Test of DCP, MCP Raw Materials. I am working as a laboratory chemist in a feed mill in Bangladesh.
[Factor 0.0313] ... This is atomic weight of phosphorus (31) devided by 1000 [The factor 25] ... This is convertion factor from phosphorus to phospholipid content
@@MicroChemsExperiments for spectrophotometry method did you determine the concentration of phophates or phosphorous ? and if it was for phosphate did you use the conversion factor of 25.5?
@@MicroChemsExperiments could you please explain it briefly here in the comment ? and also I want to know Where did this result 25.5 and 0.0013 in the Equation of calculation of Phosphorus come from ?
This is a helpful procedure. Thank you! I'd like to as, can I use other buffer solutions instead of ammonia buffer?
Thank-you sir ,can you please explain, determinatiom of wax in sun flower oil by gravimetric method ?
Noted. Will make video later
Thank you for your great videos 🙏
could you upload a video about determination of metal ions in crude edible oil ?
Okay
What is the ph for the ammonia buffer solution? 10?
Here we find the percentage of free phosphorus or what is present in the phosphatidyl compounds?

Thank you I will really appreciate
1. There is no specific temperature. Just boil the content at maybe 80 degree Celsius.
2. Buffer 10.
3. Same for all oils
This was very easy to follow, but can this procedure be used for ethanol as well? Cause I'm having a really hard time finding phosphorus content determination procedures for ethanol. It'd be a great help if you could answer ❤
No. This method is not applicable for ethanol.
@@MicroChemsExperiments Okay, thank you!
This is process called Degumming of Vegetable Oils.
Can EDTA be used instead of disodium EDTA?
Is it possible to calculate the amount of iron in edible oil using EDTA and how?
Help me please
Thanks for video and keep it
Sunil Yadav, you are most welcome. Be with us.
Here we find the percentage of free phosphorus or what is present in the phosphatidyl compounds?
ThanQ so much for the procedure,phosphorous content method results are same as Spectroscopy method? ,i wnated to test for crude palm oil.
Yes, same. You can test in your lab and compare both results
what is the temperature acetone need to be heated? according to a previous comment you have mentioned to 80C. bout acetone boiling point is 56C. is it okay to heat around 45C?
No matter of 80 degree or 56 degree. Just apply heat and stop when start boiling and remove the flask from heating mantle

Is there by any chance that you could tell me how this value was derived, or give me a link to a material that can maybe make the reason clearer why this is the value for the calculation factor? Thank you very much!
In reference, this method is not mentioned clearly. We develop this method internally using the basic of that reference.
was the formula that you used for phosphorus content based from the formula for percent chloridate titrated? it is the only formula from the reference book that i have found to be somewhat related, it is in page 205.
were you able to know why he used that calculation factor? and can you please tell me the page of the book from which you found the reference
@MicroChem's Experiments is this procedure is applicable in the determination of phosphorous content in RBD oil (Refined Bleach Deodorized Oil)?
Yes. Applicable
Hi what is the specific edible oil in the video and does that factor 0.0313 apply to all kinds of oil as in can I use it for sunflower soyabean or any other oil
It was crude soybean oil. Factor is the same for all kind of oils
It would be beneficial to share the Calcium Test of Limestone Grid and Calcium and Phosphorus Test of DCP, MCP Raw Materials. I am working as a laboratory chemist in a feed mill in Bangladesh.
Okay we will develop
please guide me method of gum determination through phosphoric acid
Follow the method as described in this video
What method is used for? AOCS or some other,please?
Reference is given by at the very first of this video. Please play this video again and find the reference out
Please tell me the difference between spectrophotometer and this test
Spectrophotometric test is more appropriate
thank you !!!
Sitti Mujur Channing Usman Duri, you are most welcome.
MicroChem's Experiments btw sorry for asking what is 0.313x10^6 stand for ??
may i know where you got that formula ?? please 😅
@@Jukchanning Please check the reference mentioned in the video title.
@@Jukchanning These are given by FAO to simplify the method.
Is the result matches with spectrophotometer method result?
i think no
@@chemistbd886 how do you determine it with spectrophotometer?
Ammonia solution and Ammonia buffer solution are the same?
Yes. Same
if I use Ammonia solution, what is the concentration allowed to use?
I want to know Where did this result 25.5 and 0.0013 in the Equation of calculation of Phosphorus come from ?
These are calculation factors
[Factor 0.0313] ...
This is atomic weight of phosphorus (31) devided by 1000
[The factor 25] ...
This is convertion factor from phosphorus to phospholipid content
Where I get details of this reaction ,name of this reaction?
Not well known. You can study the reference given in the video title. Thank you.
What is the initial volume reading, is it refer to blank?
It's the initial burette reading which we got before starting the titration.
@@MicroChemsExperiments if there is any experiment for sulfur content determination in oil available?
@@basmaali5534 Not yet. We will develop a video later. Stay with us.
What is the reference for this method .. Thank you very much
Reference Method is mentioned in the first of this video. Please check it out.
Does this method work if phosphorus content in oil is below 10ppm level?
Yes but in that case you have to use 0.001M EDTA solution during titration
what is 0.0313 x 1000000 stand for ?
whtat is 25.5 number stand for ?
Factors
Thx, Foctors for what?
How can determine calcium and magnesium in edible oil sir
You need to follow AAS method
spectrophotometer instrument not possible?
IF WE GOT SPECTROPHOTOMETRIC METHOD THEN WE WILL BE THANKFUL.
We will try
@@MicroChemsExperiments for spectrophotometry method did you determine the concentration of phophates or phosphorous ? and if it was for phosphate did you use the conversion factor of 25.5?
how can I calculate iodine value by colorimetry of vegetable oil ?
Sorry, we didn't make colorimetric video
@@MicroChemsExperiments could you please explain it briefly here in the comment ? and also I want to know Where did this result 25.5 and 0.0013 in the Equation of calculation of Phosphorus come from ?
