钴的极谱测定方法很多,但通常都要预先进行分离,而且灵敏度不高,只适宜较高含量钴的测定。对于矿石中微量钴的极谱测定,所见到资料较少。我们Шпигун在等资料的基础上,对钴-丁二肟络合物在柠檬酸铵底液中所产生的催化波进行了有关条件实验;并发现有盐酸羟胺的存在,大大提高了 Cobalt polarographic determination of many ways, but usually have to be separated in advance, and the sensitivity is not high, only suitable for the determination of higher cobalt content. Polarographic determination of trace cobalt in the ore, see less information. We Шпигун on the basis of other information, the cobalt-butadiene dioxime complex in ammonium citrate at the bottom of the catalytic wave generated by the experimental conditions and found that the presence of hydroxylamine hydrochloride, greatly increased
