等曾建议用铬偶氮酚KS(Chromazol KS) 作为光度法测定铝的试剂。它是2-羟基-3-羧基-5-磺基苯-1-(1-偶氮-2′-)-1′,8′-二羟基萘-3′,6′-二磺酸的三钠盐: 本工作研究铬偶氮酚KS与铝的反应
It has been suggested that chromazol KS should be used as a reagent for the determination of aluminum by spectrophotometry. It is tris (hydroxy) -3-carboxy-5-sulfobenzene- 1 - (1-azo- 2’-) - 1 ’, 8’-dihydroxynaphthalene-3’, 6’-disulfonic acid Sodium salt: This work is to study the reaction of chromium azo-phenols KS with aluminum
