摘要
研究了铜与铬天青S(CAS)、溴化十六烷基三甲基铵(CTMAB)三元配合物的显色反应.通过与Cu CAS二元系统的显色反应的对照证明:阳离子表面活性剂溴化十六烷基三甲基铵的加入,使得显色反应的灵敏度大幅度提高,最大吸收波长由590nm(二元系统)→626nm(三元系统),红移36nm,而且三元系统的稳定性较二元系统更高,可在短时间内迅速显色,并在较长时间内保持稳定.
In this paper,(CTMAB) tricomplex compound color reaction Copper, chrome azurol S(CAS)and Hexadecyltrimethylammonium bromide was studied. In comparison with CuCAS bicomplex compound color reaction, the sensitivity of trisystem color reaction was increased greatly resulting from the adding of cation acrosol Hexadecyltrimethylammonium bromide. It is also showed that the stability of trisystem was better than that of bisystem and the color reaction developed in very short time and kept stable for long time.
