摘要
研究了新试剂４－（Ｈ酸偶氮）－１－苯基－３－甲基吡唑酮（ＨＡＰＭＰ）与铝的显色反应，在ｐＨ４．６的ＨＡｃ－ＮａＡｃ缓冲介质中，ＣＴＭＡＢ存在下，ＨＡＰＭＰ和Ａｌ（Ⅲ）反应生成２∶１红色络合物，λｍａｘ＝５５５ｎｍ，ε＝１．３４×１０５Ｌ·ｍｏｌ－１·ｃｍ－１，铝的含量在０～３．５μｇ／２５ｍＬ内符合比尔定律，方法已用于天然水样中铝的测定。
he color reaction of 4(Hacidazo)
1phenyl3methylpyazolone(HAPMP) with aluminium() was studied.In pH4.6 HAcNaAc buffer
solution and CTMAB medium,HAPMP reacts with Al() to form a 21 stable red complex.The molar
absorptivity is 1.34105Lmol-1cm-1 at 555nm.Beer's law is obeyed in the range of 03.5g
Al/25mL.This method has been applied to the determination of aluminium in water with
satisfactory results.
