Abstract:

Labile fluoride in soil samples was extracted using sodium citrate - EDTA, sodium citrate - TISAB II, ammonium lactate, IMhydrochloric acid and water. Hydrochloric acid was found to give the highest fluoride level while water gave the lowest fluoride level.Shaking time andamount of sample showed that 1 1/2 hours shaking and lgm sample gave the best results with ammonium lactateextracting media Recovery of fluoride using ammonium lactate was found to be 90-100% efficient while medium clay samples gaveless than 90% fluoride.
