例 3-17 某溶液中含Zn2+ 、Cd2+两种离子，其浓度分别为C(Zn2+ ) = 2.93×10-5 mol•dm-3 ，C(Cd2+ ) = 1.40×10-6 mol•dm-3。向该溶液中不断 通入H2S，使溶液中H2S保持饱和(H2S的饱和浓度为0.10 mol•dm-3 )

Solubility limit for P at 1273 K is Co 2 1 x 10 cm\. Intrinsic carrier concentration is 10 cm\. Thus, before including higher order terms, Do=13x10-4 cm2/s. But with first order and second order correction terms
