摘要
实验合成了２，４———二硝基偶氮胂（简称ＤＮＡＡＳ），研究了它的红外、差热分析、元素分析等表征，并对其在光度法测定微量铜中的应用进行了研究，测定了江西省出产的部分食品中铜含量，与常规方法相比较，用２，４—二硝基偶氮胂测定铜含量的准确性较好，而且方法简单可行．
dinitrtophenyl)-azo]-7-[(2-arsenophenyl)-azo]-1.8-dinhydroxynaphthalene-3.6-disulfonic acid is synthesized and characterized by elemental analysis ,IR,differential thermal analysis.And its application on photometric microdetermination of copper in food is researched.The result of comparing with normal way shows that the approach offered in this paper is accurate and practicable.
