多参数跟踪装置研究盐和复盐溶解动力学

STUDY ON THE DISSOLUTION KINETICS OF SALTS AND DOUBLE SALTS BY A MULT-PARAMETER TRACING SYSTEM

采用微机与多台分析仪联机装置，测定了钠硼解石溶解过程中Ｎａ＋Ｃａ２＋电位及ｐＨ值、电导率值的变化，改进联机装置为一机多用的采集系统，并对氯柱硼镁石在水中溶解的Ｍｇ２＋，Ｃｌ－，Ｈ＋电位等进行自动采样、储存、打印，编制了动力学所需数据处理程序，可进行电极校正，将测定值直接校为浓度，作出Ｃ－Ｔ的动力学曲线及计算动力学方程等，所得结果表明该装置对反应快或慢的体系均能同步而且准确地得出多种参数的实测值，在化学、生物海洋和医药领域等方面的应用具有推广意义。

The changes of Sodium and Calcinm ionic voltage,pH value and electrical conductivity have been studied in the dissolving process of Ulexite by the connecting system of microcomputer and sevral analysis devices.The system has been developed into a collecting system of using one ionic analysis device.The voltages of Mg(2+),Cl-,H+ during the dissolution in water of Chloropinnoite have been collected, stored and printed.The needed Kinetics programs have also been designed.The results show that the system can determine various parameter of both fast and slow reactions at the same time.It can also be used in chemistry,marine biology and medicine.
