摘　　要：[目的]研究植酸海泡石复合重金属吸附剂对Pb2+的吸附效果。[方法]利用植酸和海泡石复合制备出植酸海泡石复合重金属吸附剂,并研究了其对Pb2+的吸附效果。[结果]植酸海泡石复合重金属吸附剂对Pb2+有很好的吸附效果,最佳吸附剂用量为20 g/L,最佳吸附温度为40℃,最佳吸附pH为4。该吸附剂可再生、便于重复利用。[结论]植酸海泡石复合重金属吸附剂将在废水处理领域拥有广阔的前景。[Objective] The research aimed to study Pb2＋ adsorption effect by phytic acid and sepiolite composite adsorbent of heavy metal. [Method] By using phytic acid and sepiolite, composite adsorbent of heavy metal was prepared, and its adsorption effect on Pb2＋ was studied. [ Result ] Phytic acid and sepiolite composite adsorbent of heavy metal had very good adsorption effect on Pb2 ＋. The optimum adsorbent dosage was 20 g/L, the optimum adsorption temperature was 40 ℃, and the optimal adsorption pH was 4. The adsorbent could be regenerated and was convenient for repeated utilization. [ Conclusion ] Phytic acid and sepiolite composite adsorbent of heavy metal would have broad prospect in wastewater treatment field.
