铟及其化合物在电子、合金、催化剂等领域有着广泛的应用,铟又是人体所需的几十种微量元素之一,但摄入量过多会引起酶的失活。可溶性的铟化合物毒性大,特别是对肝脏和肾脏造成损伤;随着铟的进一步开发和利用,也带来了环境污染问题。因此对铟进行微量分析非常重要,利用铟与配体进行电化学和光谱测定,是铟分析的重要方法。In(Ⅲ) 次外层 s, p电子全充满, d和f 电子全空, 能与N, O配位。2,2-联吡啶具有容易给出孤对电子的性质,因此也容易于有空的d或f轨道的金属络合,是重要的贵金属络合配位体。 在*********缓冲溶液中,用循环伏安法(CV) 可见光光谱研究了In(Ⅲ) 与2,2-联吡啶(bpy) 的相互作用。结果表明:In(Ⅲ) 离子的循环伏安图呈现一对准可逆的氧化还原波,bpy与In(Ⅲ) 作用后, In(Ⅲ) 的氧化还原峰电流明显降低、 式量电位正移,In(Ⅲ)与b p y 作用后,bpy的可见光谱发生了明显变化,可见光谱表明 In(Ⅲ) 与 b p y 结合比为1: 2。

帮帮忙 我也翻译了 但是希望更加通顺一些 希望大家能帮忙翻译一下

In electronics, and compounds indium alloy, catalyst etc widely used, and the human body needs of indium is one of several kinds of trace elements, but excessive intake causes the enzyme. Soluble indium toxic compounds, especially to the liver and kidney damage, With the further development and utilization of indium, also brought the environmental pollution problems. So for trace analysis of indium is very important, with ligands are using indium electrochemical and spectrometric analysis is an important method of indium. In Ⅲ (s) times the outer, p, d and electronic electronic empty, f O N and coordination. Al is easy pyridine viewpoint - to electronic properties are solitary, therefore also easy to free d or f orbit, is an important part of metal complex metal complex ligand. In * * * * * * * * * buffer solution, by cyclic voltammetry (CV) visible spectra Ⅲ (studied) and In bpy viewpoint - united pyridine (the) interaction. Results show that: (Ⅲ) ions In the cyclic voltammograms a
