| Abstract: | Objective To study the effect of DTF reagent on defluoridation for tea fluoride.Method Observed the effect of DTF reagent on defluoridation in different methods of making tea process by adding the reagent into tea or water.Results In methods of soaking tea in hot water or boiling tea(1.0 g tea,200 ml water)a dose of 0.2 g reagent could decrease the level of tea fluoride about 60%,and reduce fluoride level from 2.0 to 4.0 mg/L to about 1.0 mg/L.No changes were found in pH,tea color and taste of tea water by this method.Conclusion The reagent of DTF is an effective reagent for defluoridation of tea fluoride. |
