摘要
采用测试和回归方程求极限的方法 ,研究了NH4Cl掺入下 ,5(NH4)2O·12WO3·5H2O的平衡溶解度。结果表明 ,当NH4Cl浓度为1mol/L、2mol/L、3mol/L时APT的溶解度分别为NH3·H2O -H2O系的1/2、1/3、1/4。NH4Cl浓度<1.5mol范围内 ,其对APT溶解度的影响较为明显。NH4Cl浓度>1.5mol/L后影响减弱。
This paper makes a research on the equilibrium solubility of 5(NH4)2O·12WO3·5H2O with NH4Cl by adopting test and regression equation limit methods. The reserch results show that the concentration of NH4Cl are 1mol/L, 2mol/L and 3 mol/L respectively, the solubility of NH3·H2O-H2O system are 1/2, 1/3 and 1/4. The effect on APT solubility is clear when the concentration range of NH4Cl is less than 1.5mol. The effect is thinner when the concentration of NH4Cl is bigger than 1.5mol/L. The effect of temperature on APT solubility with NH4Cl is less.
