硒、碲性质相似,在矿石和其它物料中,往往同时要求测定。在某些底液中它们虽可产生极谱波,但峰电位不是相距很近,就是其中之一波形较差,影响定量测定。在氯化铵-氨底液中,硒波与氨波相近,波形较差。在亚硫酸钠-碳酸钾底液中,则硒波不够稳定,因此现有同一底液中同时测定硒、碲的方法都不够理想。为了探求同一底液测定硒、碲较好的条件,曾对多种支持电解质进行了试验,发现经亚硫酸盐处理,使硒成硒代硫酸盐后,在微氨性的酒石酸钠底液中,硒、碲波高稳定,波形良好,从而拟定了用酒石酸钠-亚硫酸钠为支持电解质,在 pH8～10时连续测定硒、碲的方法,其优点是硒波在碲波之前,峰电位分别为 Selenium and tellurium are similar in nature and are often required for both ore and other materials. Although in some of the bottom liquid they produce polarographic waves, but the peak potential is not very close, that is, one of the poor waveform, affecting the quantitative determination. In the ammonium chloride - ammonia solution, selenium and ammonia wave similar, poor waveform. In the sodium sulfite - potassium carbonate bottom solution, then the selenium wave is not stable enough, so the same method for simultaneous determination of selenium and tellurium in the same bottom solution is not ideal. In order to explore the same end of liquid determination of selenium, tellurium better conditions, a variety of support electrolytes have been tested and found that the sulfite treatment, the selenium into seleno-sulfate, in the micro-ammonia sodium tartrate solution , Selenium, tellurium wave height and stability, good waveform, which developed with sodium tartrate - sodium sulfite as support electrolyte, at pH 8 ~ 10 continuous determination of selenium and tellurium, the advantage of selenium wave in the tellurium wave, the peak potentials were
