| 摘 要： | 合成了新试剂４－（Ｈ－酸偶氮）１－苯基－３－甲基吡唑酮（ＨＰＭＰ），研究了其和铜的显色反应。在ｐＨ＝７的ＮＨ４Ａｃ缓冲介质中，ＣＴＭＡＢ存在下，ＨＰＭＰ与Ｃｕ（Ⅱ）生成２∶１紫色络合物，λｍａｘ＝５８０ｎｍ，ε＝５．６８×１０４Ｌ·ｍｏｌ－１·ｃｍ－１。铜含量在０～０．６ｍｇ／Ｌ内符合比耳定律。方法用于水样和生物样品中铜的测定，结果令人满意。

| Abstract: | 4-(H-acidazo)1-Phenyl-3-methylpyazolone(HPMP) was synthesized and identified,and the color reaction of HPMP with copper was studied.In PH=7 NH-4AC buffer solution and CTMAB medium,HPMP can reacts with Cu() to form a violet 2:1 complex.The molar absorptivity is 5.6810+4Lmol+{-1}cm+{-1} at 580nm.Beer's law is obeyed in the range of 0-0.6 mg/L.This method has been applied to the determination of copper in water and food with satisfactory results.= |
