氯、溴离子选择性电极的制备,文献已有报导,我们在制备了碘电极的基础上,又用卤化银和高纯银粉为电活性材料制备了普通型,小型杯状和针状氯、溴离子选择性电极。这三种不同形状的氯、溴离子选择性电极,可以测定1×10~0-5×10~(-5)M的氯离子和1×10~(-1)-3×10~(-6)M的溴离子。小型氯,溴离子选择性电极可以测定20μl样品溶液中的氯、溴离子。我们用自制的氯、溴离子选择电极测定了北京401地区水源井中的氯,溴离子,方法简便,结果满意。
Chlorine, bromide ion selective electrode preparation, the literature has been reported, we have prepared on the basis of iodine, silver halide and high purity silver powder as the electroactive material prepared by ordinary, small cup and needle chlorine, Bromide ion selective electrode. The three kinds of chloride and bromide ion selective electrodes with different shapes can measure the chloride ion of 1 × 10 ~ 0-5 × 10 ~ (-5) M and 1 × 10 ~ (-1) -3 × 10 ~ (- 6) M bromide ion. Small chlorine, bromine ion selective electrode can be measured in 20μl of sample solution of chlorine, bromide. We measured the chlorine and bromine ions in water wells in Beijing 401 area with homemade chloride and bromide ion selective electrodes. The method is simple and the results are satisfactory.
