华惠珍等曾研究过锑的氢催化波,发现在含0.4M氯化钠,0.2M盐酸或3.6V磷酸的钴盐溶液中均有锑的氢催化波。其主要研究的体系是在pH 2时的0.4M硫酸钠,10~(-4)M硫酸钴溶液。作者研究了盐酸、钴盐体系中的氢催化波,发现盐酸浓度在0.5—10M之间,在一定的锑量和钴盐浓度时均能产生氢催化波。由于盐酸对某些物质的可溶性和省却调节pH值等优点,在该一底液中的锑的氢催化波是有利于分析上应用的。在测定0.05—1微克锑/毫升时,最宜的测定条件是2M盐酸,10~(-3)M氯化钴、10~(-4)M溴化四丁基铵。当把盐酸浓度改为1M时,可测0.015微克锑/毫升。
Hua Huizhen et al. Have studied the hydrogen catalytic wave of antimony and found that there is a hydrogen catalytic wave of antimony in a cobalt salt solution containing 0.4 M sodium chloride, 0.2 M hydrochloric acid or 3.6 V phosphoric acid. Its main research system is 0.4M sodium sulfate, 10 ~ (-4) M cobalt sulfate solution at pH 2. The authors studied the hydrogen catalytic wave in the hydrochloric acid, cobalt salt system and found that the concentration of hydrochloric acid between 0.5-10M, at a certain amount of antimony and cobalt salt concentration can produce hydrogen catalytic wave. Due to the solubility of hydrochloric acid for some substances and the advantages of saving pH value, etc., the hydrogen catalytic wave of antimony in the bottom liquid is advantageous for analysis. In the determination of 0.05-1 micrograms of antimony / ml, the most suitable measurement conditions are 2M hydrochloric acid, 10 ~ (-3) M cobalt chloride, 10 ~ (-4) M tetrabutylammonium bromide. When the concentration of hydrochloric acid to 1M, 0.015 micrograms of antimony can be measured / ml.
