摘要

采用强酸性阳离子交换树脂001×7苯乙烯系磺酸钠型树脂为载体

负载H+

Al3+和La3+制成3种球状吸附剂.研究结果表明:改性树脂较未改性树脂可显著提高对水中氟离子的去除效率;吸附时间

外界氟离子浓度

树脂量

pH值对于3种改性树脂的除氟效率都有影响

其中Al改性树脂除氟效果最好

其最佳除氟条件是:吸附时间为16 h

吸附浓度为12 mg/L

4 mg树脂量

酸性条件.

Abstract

The cation-exchange resin(001×7) is chosen as adsorption

which is transformed by different solutions(H+

Al3+ and La3+).Results show

comparing with non-modified resin

modified resin can improve defluridation efficiency from water;removing rate of fluoride of these three kinds of resin can be influenced by time

concentration of fluoride in water

weigh of resin and pH;model-Al resin has the highest defluoridation rate

and the best conditions are: adsorption time is 16h

concentration of fluoride in water is 12 mg/L

weigh of resin is 4 mg

acid condition.
