摘要

在水解法制备氯氧化铋的反应结晶过程中，氯氧化铋在盐酸溶液中的溶解度数据至关重要。采用平衡法测定了303.15～363.15 K范围内氯氧化铋在盐酸溶液中的溶解度，并用Apelblat方程、经验多项式方程、λh方程对实验数据进行关联。结果表明：氯氧化铋溶解度随着盐酸浓度和温度的升高而增加，盐酸的浓度对氯氧化铋溶解度的影响更为显著；上述3种模型都可用于关联氯氧化铋的溶解度与温度的关系，就BiCl3-HCl-H2O体系而言，Apelblat方程、经验多项式方程和λh方程的拟合精度分别为0.99、0.98和0.93， Apelblat方程的模拟结果最佳。

Abstract

For bismuth oxychloride (BiOCl) precipitation from BiCl3-HCl-H2O system

it is important to obtain its solubility in hydrochloric acid solution and correlate the data between bismuth oxychloride solubility and some parameters

such as temperature and pH value. In this study

solubility of BiOCl in hydrochloric acid solution was experimentally determined by the equilibrium method in the temperature range from 303.15 to 363.15 K. The experimental data are correlated by Apelblat equation

Empirical equation and λh equation. The results show that BiOCl solubility increases with the increase of temperature and concentration of hydrochloric acid solution. The concentration of hydrochloric acid solution has greater effect than temperature on the solubility of BiOCl. The solubility data for BiCl3-HCl-H2O system are well correlated by Apelblat equation

Empirical equation and λh equation

with the fitting accuracies of 0.99

0.98 and 0.93

respectively

among which Apelblat equation is the best.
