水中硫化物的测定方法有碘量法和对氨基二甲基苯腙比色法,皆需对水样进行前处理,手续麻烦,而极谱法测定时手续简单,据报道,硫离子在0.5MNa_2B_4O_7-0.02M NaOH底液中,在汞电极上能呈现阳极波,其反应机理如下: Hg+S~(2-)→HgS+2e 亦有在铜-氨基乙酸介质中测定,硫离子能产生灵 Determination of sulfide in water with iodometric method and p-aminophenylhydrazone colorimetry, are required for pre-treatment of the water sample, procedures cumbersome, while the polarographic determination of the procedure is simple, it was reported that the sulfur ions at 0.5 MNa_2B_4O_7-0.02M NaOH electrode solution, the mercury electrode can present anodic waves, the reaction mechanism is as follows: Hg + S ~ (2-) → HgS + 2e is also measured in the copper-amino acetic acid medium, sulfur ions can produce spirit
