比较详细地研究了Hg_2Cl_2-HgS压膜式全固态氯离子选择性电极的制备条件,提出一个较为简易的制备方法。测试了电极的主要性能和参数。电极对Cl~-的线性检出下限约3×10~(-6)M(0.10微克/毫升),探测极限约5×10~(-7)M(0.02微克/毫升)。用于实际样品分析,得到满意的结果,精度优于5%。 The preparation conditions of Hg_2Cl_2-HgS pressed-film all-solid-state chloride ion selective electrode were studied in detail, and a simple and easy preparation method was proposed. The main properties and parameters of the electrode were tested. The linear detection limit of Cl ~ - was about 3 × 10 -6 M (0.10 μg / ml) and the detection limit was about 5 × 10 -7 M (0.02 μg / ml). For actual sample analysis, satisfactory results are obtained with an accuracy of better than 5%.
