摘要： A cationic adsorption agent which is obtained by reaction of(a) an amino compound which contains at least one amino group and at least one free or methylolated carbamide or thiocarbamide group, or a salt thereof, with(b) an aminoplast precondensate which does not contain amino groups.The novel adsorption agent is suitable in particular for removing anionic substances, such as acid dyes or reactive dyes, from aqueous solutions, especially from wastewaters.

摘要翻译： 通过（a）含有至少一个氨基的氨基化合物和至少一种游离或羟甲基化的脲或硫代氨基甲酰胺或其盐与（b）氨基塑料预缩合物反应得到的阳离子吸附剂， 含有氨基。 新颖的吸附剂特别适用于从水溶液，特别是废水中除去阴离子物质，如酸性染料或活性染料。
