Introduction of GB/T 12154-2008

本标准规定了锅炉用水和冷却水中全铝的测定，适用于锅炉用水和冷却水中全铝含量为2μg/L~500μg/L的测定，也适用于饮用水、地下水和轻度污染的地表水和海水中铝离子的测定。本标准对应于ＩＳＯ１０５６６：１９９４《水质　铝的测定　邻苯二酚紫分光光度法》（英文版），与ＩＳＯ１０５６６：１９９４的一致性程度为非等效。
本标准代替ＧＢ／Ｔ１２１５４—１９８９《锅炉用水和冷却水分析方法　全铝的测定》。
本标准与ＧＢ／Ｔ１２１５４—１９８９的主要差异为：
———ＧＢ／Ｔ１２１５４—１９８９中可溶性铝与试铁灵（７-碘-８-羟基喹啉-５-磺酸）反应，生成稳定的黄色络合物，在波长３７０ｎｍ处测其吸光度；本标准中铝与邻苯二酚紫（Ｃ１９Ｈ１４Ｏ７Ｓ）在ｐＨ值为
５．９±０．１时反应生成蓝色络合物，在波长５８０ｎｍ处测其吸光度。
