| 摘 要： | 介绍了新显色剂2-磺酸基苯基-1,4-二氨基重氮偶氮苯的合成及其与镍(Ⅱ)的显色反应。实验表明,在非离子表面活性剂Triton X-100的存在下,在pH10.5的硼砂—氢氧化钠缓冲介质中,镍(Ⅱ)与SDADA形成量比=1∶3的红色络合物,在545 nm处有一最大吸收峰,在433 nm处有一最大负吸收峰。镍(Ⅱ)质量浓度在0.12~0.28μg/mL的范围内符合比耳定律,表观摩尔吸光系数为9.60×105L.mol/cm。

| Abstract: | A new chromogenic reagent 2-sulfobenzene-1,4-diamino diazoazobenzene was synthesized and its colour reaction with nickel(II) was studied.The reagent was reacted with nickel(II) to form a red complex in the medium of borax-sodium hydroxide buffer solution(pH10.5) with the existence of nonionic surfactant Triton X-100.The molar ratio of the complex was 3:1,with the maximum absorption at 545 nm and the miximum negative absorption at 433 nm.Beer's law was obeyed in the range of 0.12~ 0.28 mg of nickel in 25 ml solution,with the apparent molar absorptivity of 9.60×105 L× mol/cm. |
