海藻酸钠%吸附%Cr3+
海藻痠鈉%吸附%Cr3+
해조산납%흡부%Cr3+
sodium alginate%adsorption%Cr3+
以海藻酸钠（ SA）为吸附剂去除水中的Cr3＋，考察了pH和吸附时间、SA的用量等因素对吸附行为的影响。试验结果表明，吸附过程在2 h 左右达到平衡；在 pH＝6时吸附效果达到最佳；当 Cr3＋的初始浓度为500 mg／L时，吸附剂的最佳用量以0．6 g为宜，且吸附过程符合Freundlich等温吸附模型。对吸附材料进行傅立叶红外表征，结果－OH基团和C＝O基团是吸附Cr3＋的主要基团。

The adsorption of sodium alginate to Cr3+ was discussed.Some factors,such as pH and adsorp?tion time,the dosage of sodium alginate were investigated.The results showed that the adsorbing effect was the best when pH was about 6.0,and the adsorbing equilibrium appeared in about 2 hours,and the best dosage of sodium alginate was 0.6 g when the concentration of Cr3+was 500 mg/L.The adsorption process fit well to the Freundlich isotherm model.The composite adsorbents were characterized and analyzed by FTIR.The results in?dicated that the major groups of adsorption were the-OH group and the C=O group.
