Table S1: Treatments of Batch Experiment 1. The added Cd concentrations were measured in the corresponding control treatments without sorbent (mean ± SE, N = 3). The pH values were measured after 2 hours agitation (mean ± SE, N = 5, 4 or 3 according to the number of Cd levels).表S1：批量试验1的处理。添加的Cd浓度在未加吸附剂的相应对照处理中测定（平均值 ± 标准误，N = 3）。pH值在振荡2小时后测定（平均值 ± 标准误，根据Cd水平数，N = 5、4或3）。
