钴-丁二肟络合物在柠檬酸铵中的氢催化波在国内外已有不少报导。文献研究了钴-丁二肟络合物在柠檬酸铵中并有盐酸羟胺的存在下,大大提高了原方法的灵敏度,并使波形进一步得到了改善。对于水中痕量钴的测定仍感到灵敏度不够理想,因此在文献的基础上加大了盐酸羟胺的用量,同时针对水分析重新做了有关条件实验,拟定了一个适合于水中痕量钴的快速极谱测定的方法,最低可测至 Hydrogen-catalyzed waves of cobalt-butadiene dioxime complexes in ammonium citrate have been reported at home and abroad. The literature studies the cobalt-butadiene dioxime complex in the presence of ammonium citrate and hydroxylamine hydrochloride to greatly enhance the sensitivity of the original method and to further improve the waveform. For the determination of trace amounts of cobalt in water still feel the sensitivity is not ideal, so based on the literature to increase the amount of hydroxylamine hydrochloride, while water analysis to re-do the relevant experimental conditions, developed a suitable for trace cobalt Spectral determination method, the minimum measurable
