用改性剂对茶叶进行改性,用于处理含氟废水,探讨了改性剂浓度、pH值和改性茶叶投加量对除氟效率的影响,绘制了吸附等温线.实验结果表明,0.3 mol/L的FeCl3溶液对茶叶的改性效果最佳.对于100 mL含氟浓度为100.0 mg/L的溶液,改性茶叶除氟的最佳pH为6.0,最佳投加量为1.3 g.改性后的茶叶对氟的吸附符合Freundlich等温吸附公式,饱和吸附容量为15.75 mg/g.

Tea was modified by reagent,and the removal of fluorine from wastewater using modified tea was studied.The effect of pH,modified reagent concentration and dosage of modified tea on the removal rate of fluorine were investigated.Adsorption isotherm was established.The results showed that for 0.3 mol/L FeCl3 solution showed the best effect on the modification of a 100 mL fluorine solution (containing was 100.0 mg/L fluorine),the optimum pH value of 1.3 g modified tea in removing fluorine were 6.0.Moreover,it was showed that adsorption of fluorine for modified tea conformed to Freundlich adsorption isotherm.
