2012年5月1日 It can be observed from Fig. 3 a that zinc forms only one cationic species (ZnCl +) under the experimental conditions.The soluble zinc species are stable up to a pH of about 6, after which zinc precipitates as Zn 2 (OH) 3 Cl. It is also evident that ZnCl + cations contribute a very small amount as compared to Zn 2 +.. Contrary to zinc, cadmium forms
