摘要： 本文研究了在阴离子表面活性剂十二烷基硫酸钠(简称SLS)存在下,铜(Ⅰ)与5[(3,5-二溴-2-吡啶)偶氮]-2,4-二氨基甲苯(简称3,5-二溴-PADAT)的显色反应和光度特性,试验了用该体系测定微量铜的条件和方法。

Abstract: Asensitive, practical colour reaction of copper(Ⅰ)-5-(3,5-dibromo-2-pyridy-lazo)-2,4-diaminotolucne-sodium lauryl sulfatc sulfactanls has been investigated spe-ctrophotomctri cally. The complex of copper (Ⅰ) was formed at about pH3.0 The apparent molar absorptivity was 8.26×104 at 492 nm.
