摘要
通过对酸性介质中对苯二胺抑制Na2CO3-NaNO2-H2O2体系的化学发光进行研究,建立了一种流动注射-抑制化学发光测定染发剂中对苯二胺的方法。实验结果表明,在所选择的优化条件下,对苯二胺溶液的质量浓度与化学发光强度的降低值呈良好的线性关系,对质量浓度为1.0×10-4 g.L-1的对苯二胺溶液进行11次平行测定的相对标准偏差为0.58%,检出限为1.5×10-7 g.L-1。
Through the study on chemiluminescence intensity inhibition effect of p-phenylenediamine on Na2CO3-NaNO2-H2O2 system,a flow injection analysis method for determination of p-phenylenediamine content in hair dye product was established.Experimental work results showed that,under the selected optimal conditions,the p-phenylenediamine solution mass concentration and the reduction of the value of the chemiluminescence intensity displays good linear relationship.In eleven parallel tests carried out with p-phenylenediamine solution of mass concentration of 1.0×10-4 g·L-1,the relative standard deviation is 0.58%,and the detection limit is 1.5×10-7 g·L-1.
