微量铝的测定方法发展很快。所涉及到的显色剂多属酚羧酸三苯甲烷染料,如铬天青S、铬菁 R、铬天青 B 等。新近,人们把注意力转移到具有优良性质的2,3,7-三羟基-9-取代萤光酮类显色剂上,相继报道了利用水杨基萤光酮、二溴苯基萤光酮作为铝的显色剂而建立的新的光度分析方法。上述方法,有一共同特点就是采用胶束增溶手段后,方法都具有很高的灵敏度。 Determination of trace amounts of aluminum developed rapidly. Most of the developers involved are phenolic carboxylic acid triphenylmethane dyes, such as chrome azure S, chrome cyanide R, chrome Azure B and so on. Recently, attention has been shifted to 2,3,7-trihydroxy-9-substituted fluorone ketones with excellent properties. Selectively using salicylfluorone and dibromophenyl fluorone as A new photometric method for the determination of aluminum as a developer. The above method, a common feature is the use of micellar solubilization means, the method has a high sensitivity.
