摘　　要：以不同材料固定化浮游球衣菌S9制备不同生物吸附剂,研究固定化后浮游球衣菌S9对铅离子吸附条件的效果和影响,发现以海藻酸钠包埋浮游球衣菌S9制得的生物吸附剂对铅离子的吸附效果最佳,其吸附量和吸附率分别为2.2mg/g和70.34%;通过单因素和正交实验,获得其最佳的吸附条件为铅离子初始浓度为40mg/L,吸附温度30℃,吸附p H 6.5,吸附时间为20min,在此条件下,生物吸附剂对铅离子的吸附量和吸附率分别达到3.04mg/g和75.80%.Different biological adsorbent prepared with Sheath bacteria S9 immobilized by different materials; and the effect and influence of immobilized Sheath bacteria S9 on lead ion adsorption were studied. It was found that the biological adsorbent with sodium alginate was the best, and the adsorption capacity and adsorption rate were 2.2mg/g and 70.34% respectively. The optimum adsorption conditions for lead ion were identified by single factor and orthogonal experiments, with initial concentration of 40 mg / L, the adsorption temperature of 30℃, p H 6.5, adsorption time 20 min. On these conditions, the biological adsorbent for lead ion adsorption capacity and adsorption rate reached 3.04mg/g and 75.80% respectively.
