乙烷硫代磺酸乙酯及二乙基二硫化物在磷酸盐缓冲的正丙醇水溶液中(pH 6.5),均产生单波。二者可以同时测定而互不干扰。在乙烷硫代磺酸乙酯为0.57—6.4 mM和二乙基二硫化物为1.6—11 mM的浓度范围内,可以定量测定,误差在±10％以内。极谱波的性能实验表明整个电极过程为受扩散控制的不可逆电极反应。控制电位电解及毫库仑法的实验证明二乙基二硫化物的还原产物为硫醇;而乙烷硫代磺酸乙酯的还原产物则为乙硫醇及乙烷亚磺酸。 Ethane ethyl thiosulfonate and diethyl disulfide in phosphate buffered n-propanol aqueous solution (pH 6.5), all generate a single wave. Both can be measured simultaneously without disturbing each other. The concentration of ethyl ethanethiosulfonate 0.57-6.4 mM and diethyl disulfide 1.6-11 mM can be determined quantitatively within ± 10%. Polarographic wave performance experiments show that the entire electrode process is diffusion-controlled irreversible electrode reaction. Controlled potential electrolysis and coulometry experiments show that the reduction product of diethyl disulfide is a mercaptan, while the ethyl ethanethiosulfate is the reduction product of ethanethiol and ethane sulfinic acid.
