采用HG_1、NH_3、N_4OH、(NH_4)_2S等常用试剂作为组试剂,将常见的二十三种阳离子分成四个组,分组后一般不需要进行组内的再分离就可以分别鉴定各个离子。
HG_1, NH_3, N_4OH, (NH_4) _2S and other commonly used reagents as a group reagent, the common twenty-three kinds of cations are divided into four groups, the group generally do not need to be re-isolated within the group can identify each ion.
