薄层树脂相分光光度法测定痕量铝的研究

Study on the thin-layer resin phase spectrophotometry for the determination of trace aluminium

提出了利用薄层树脂相光度法测定痕量铝的新方法。铝离子在酸性介质中与茜素红形成红色络合物,将其富集在H+型阳离子交换树脂上,制作成薄层直接测定。本法具有较高的灵敏度和选择性,用于化学试剂和水中痕量铝的测定,获得了满意结果。

A new analytical method for the determination of trace aluminium with the thin-layer resin phase spectrophotometry was developedA colored complex formed by Al*# ion and alizarin red was enriched on cationic exchange resin(732#)The concentration of trace aluminium was direct determined by preparing the thin layer of cationic exchange resinThe method was possessed of higher sensitive,better selective and rapid characteresThe method has been used to determine aluminium in reagents and water with satisfactory results
