通过正交试验研究了膨润土/木质素磺酸钠接枝丙烯酰胺-马来酸酐复合吸附树脂(BLPAMA)的皂化实验。采用综合评分法和综合平衡法分析得到皂化实验的优化条件:氢氧化钠溶液浓度2.0 mol/L、皂化温度100 ℃、皂化时间2.0 h。所得皂化BLPAMA树脂在二元Pb~(2+)/Cu~(2+)溶液中对Pb2+的吸附量为1.717 mmol/g,对Cu~(2+)的吸附量为2.016 mmol/g,Pb~(2+)对Cu~(2+)的选择性吸附系数为8.500。

The saponification experiment of adsorbent composites comprising of bentonite/sodium lignosulfonate graft-polymerized with acrylamide and maleic anhydride (BLPAMA) was investigated by orthogonal experiment. The optimum conditions of the saponification were obtained through the comprehensive scoring method and integrated balance method, including the concentration of sodium hydroxide 2.0 mol/L, saponification temperature 100 ℃, saponification time 2.0 h. The adsorption capacity of the saponified BLPAMA (BLPAMA-S) for Pb2+ and Cu2+ in Pb2+/Cu2+ ...
