描述

产品介绍 溶于水,是氨羧络合剂,它具有能在碱性溶液(pH=8~11)中,与三价铁等络合成稳定性的螯合盐,亦能和稀土族元素络合成稳定的络合物。在偏酸性的条件下,其他螯合剂溶解度相对较差时(也就是pH值较低)。
别名 N-羟乙基乙二胺三乙酸;羟乙基乙烯二胺三乙酸;N-(2-羟乙基)-亚乙基二氨-三乙酸;N-(2-羟乙基)乙二胺-N,N′,N′-三乙酸;N-羧甲基-N'-(2-羟乙基)-N,N-亚乙基二甘氨酸;HEDTA;HEEDTA;Versenol;EDTA-OH;N-Carboxymethyl-N′-(2-hydroxyethyl)-N,N′-ethylenediglycine
应用 螯合剂,本品用于纺织、农业、医药、特别对稀有元素的提练。
