摘要
本文研究了锌与甲基麝香草酚蓝(MTB)和溴化十六烷基三甲基铵(CTMAB)、吐温-80(Tween-80)混合表面活性剂的显色反应.测得该配合物的组成为Zn:MTB:CTMAB(Tween-80)=1:2:3.此配合物在波长560nm处具有最大的吸收,而反应的适宜条件是pH5.5～6.5.锌含量0～50μg/50ml遵循比尔定律,方法可用于铝合金中锌的测定,结果令人满意.
This paper reports study on the colour reaction of zinc with MTB-CTMAB (Tween-80) , The complex has a composition of Zn: MTB : CTMAB (Tween-80) = 1: 2 : 3. The max of the complex is at 560nm. The suitable acidity for the complex reaction is between. pH S.5-6.5. Beer's law is obeyed for 0-50ug/50ml for zinc.This method has been used for the aaalysis of zinc in aluminium alloys -with satisfactory results.
