利用双平衡法,研究了Co(Ⅱ)-NH3-Cl--H2O体系中Co?的溶解规律,通过计算绘制了热力学平衡图,揭示了体系中各物质的平衡浓度与氨水浓度和氯离子浓度之间的关系。结果表明,在该体系中唯一存在的固相物质为Co(OH)2(S),试验验证了热力学计算结果,两者之间的偏差仅为10.13%。
The equilibrium law of cobalt in Co (Ⅱ) -NH3-Cl - H2O system was studied by using the double equilibrium method. The thermodynamic equilibrium diagram was calculated and the balance of ammonia concentration and chloride ion concentration The relationship between. The results show that the only solid phase material in the system is Co (OH) 2 (S). The thermodynamics results are validated by experiments. The deviation between them is only 10.13%.
