采用完全析因实验设计，考察了三个因素对以伊利石为吸附剂的工业废液中铜、锌离子吸附的影响。在两个水平上选择的实验因素是：(A)pH为2和7，(B)吸附剂含量为0.2g和1.6g/L−=1，(C)接触时间为10min和120min B(吸附剂含量)，A(PH)和ABTerms，它们的高水平对吸附过程有积极的影响。在吸附动力学模型中，二阶模型最好地描述了数据。伊利石是一种对工业废液中Cu2+和Zn2+有较好吸附效果的吸附剂。
In this study, a full factorial experimental design was utilized to assess the effect of three factors on the adsorption of copper (II) and zinc (II) ions in an aqueous leachate of an industrial waste with illite as adsorbent. The chosen experimental factors at two levels were (A) pH at 2 and 7, (B) adsorbent content at 0.2 and 1.6 g L− 1, and (C) contact time at 10 and 120 minB(adsorbent content),A(pH), andABterms, with their high levels, positively influenced the adsorption process. Of the adsorption kinetics models, the second order model best described the data. Illite was a reasonably effective adsorbent for Cu2+and Zn2+from aqueous leachates of industrial waste.
