报道了一种灿烂绿－聚氯乙烯膜涂层玻璃电极。该电极是将灿烂绿敏感的聚氯乙膜涂敷于ｐＨ玻璃电极表面而制得的。所制电极具有制作简单，使用方便和选择性良好等优点。其Ｎｅｒｎｓｔ响应斜率为５４．７ｍＶ／ｄｅｃ，响应线性范围为９．８×１０＾－７￣５．３７×１０＾－４ｍｏｌ／Ｌ的灿烂绿，能够直接用于灿烂绿的测定。将该电极应用于催化电位法分析，测定了环境水样中亚硝酸根的含量，结果满意。

A brilliant green-polyvinyl chloride membrane coated glass electrode has been prepared with bril liant green - tetraphenyl-broate ion - pair complex being the electroactive material. The electrode is of high sensitvity and selectivity and exhibits a Nernst response slope of 54. 7 mV 1 dec. The linear range is 9. 80 ×10-7~5. 37 × 10-4mol/L for briiliant green. The electrode has been applied to the determination of trace nitrite in environmental water s...
