研究了1,5—二(2—苯胂酸)甲(月替)测定钴的最佳条件,该试剂选择性好,10倍量的镍、铁对测定无影响。含钴量在0.5～5％的各种合金钢,均可用此法直接进行测定。
The optimum conditions for the determination of cobalt with 1, 5-bis (2-phenylacetic acid) A (monthly replacement) were studied. The reagent has good selectivity and 10 times the amount of nickel and iron had no effect on the determination. Cobalt content of 0.5 ~ 5% of all kinds of alloy steel, can be directly measured using this method.
