作者利用三硫代碳酸钾(简称K_2TTC)显色反应的催化作用曾进行了超微量Cu(Ⅱ)的测定。现又对超微量锰(Ⅱ)的测定条件作了探讨,结果,即使10倍的Cu(Ⅱ)存在时,也可
The author has carried out the determination of ultra trace Cu (Ⅱ) by the catalytic action of chromogenic reaction of potassium trithiocarbonate (K_2TTC). Now the ultra-trace manganese (Ⅱ) determination of the conditions were discussed, as a result, even 10 times the presence of Cu (Ⅱ)
