摘　　要：含干扰离子水盐体系由于离子间存在相互干扰,体系的溶解度测定比较困难,通过改进连续浊点法可快速测定水盐体系溶解度而避免了干扰离子的影响。实验采用改进连续浊点法测定了NaCl-KCl-H_2O体系323.15 K时的溶解度,实验结果与实际值进行比较,基本一致,证明了改进的连续浊点法测定含干扰离子体系溶解度是简便而可行的。It is difficult to determine the solubility of the salt water system,if there are interfering ions in the system. Improving the Flow-Cloud-Point method can determine the solubility of the salt water system accurately and efficiently. This method can also avoid the interference between the ions in the system. The solubility of the NaCl-KCl-H_2O ternary system at 323. 15 K was determined with the improved Flow-Cloud-Point method,and the measured results agree well with the actual value. This confirms that the improved Flow-Cloud-Point method can be used for the solubility determination of the salt water system that containing interfering ions,with the characteristics of simple and feasible.
