微量溴通常采用分光光度法,中子活化分析法进行测定。但这些方法由于干扰太大,生成物不固定,实验条件过于苛刻,目前,卤化物电极已广泛用于测定液、乳酪、食品、生物制药、土壤、腈以及硅酸盐矿石等试样中的卤化物。本文采用我所自制的溴离子电极,测定光色玻璃中的溴化物,结果与比色法相符。 Trace bromine is usually measured by spectrophotometry and neutron activation analysis. However, due to the interference of these methods is too large, the product is not fixed, the experimental conditions are too harsh, at present, the halide electrode has been widely used in the determination of liquid, cheese, food, biopharmaceuticals, soil, nitrile and silicate ore samples halide. In this paper, my own bromide ion electrode was used to determine the bromide in light colored glass. The result was consistent with colorimetric method.
