摘要
棉纤维经碱化后 ,依次与环氧氯丙烷、二甲胺、氯乙酸在一定条件下反应 ,生成甜菜碱型两性螯合棉纤维 ,经检测 ,该两性化螯合棉纤维对 [Cr2 O7]2 - 有较强的吸附能力 ,吸附容量达 2 2 .34mg/g ,对 [Cu]2 + 的吸附容量为 13.1mg/g。
While cotton fiber was alkalified,then dealed with epichlorohydrin,dimethylamine,chloroacetic acid at certain conditions in turn,ampholytic chelating cotton fiber was composed.The fiber exhibited high adsorptive capacity to \[Cr 2O 7\] 2- and good adsorptive capacity to \ 2+ .
