stepwise method is good to understand. Can you pls post similar video of Nalgonda technique for fluoride removal.. thanku

[@priyanka199037]

Very informative video thank you sir

[@Laboratoryanalysisofwater]

Most welcome

[@abdulrasheedkarim5295]

Clarified method on fluoride determination thanks boss. However, i did not see the use of the NaASO4 solution prepared earlier, please clarify. Thank you.

[@Laboratoryanalysisofwater]

NaAsO4 is used only in chlorinated water otherwise no

[@tunasalmonmayo3783]

Excuse me, I don't have SPANDS and Sodium meta Asenic in lab at my university. What chemicals can I use instead? 🙇🏻‍♂️🙏🏻

[@kavitasoni5564]

Very nice explanation ☺

[@Laboratoryanalysisofwater]

Thanks a lot 😊

[@ankushdongre8004]

Can we heat the sample for removal of residual chlorine

[@Laboratoryanalysisofwater]

No. on heating residual chlorine is not removed

[@ankushdongre8004]

How many minimum test can do by your prepared solution
Please make video on shulphate, nitrate,iron also
