摘要
利用MIA 3型自动分析系统的硬件 ,根据研究的需要开发了一个专用软件 ,建成适用于恒pH自动滴定系统。并对一个含氧化铁很高的砖红壤的表面羟基的释放过程进行了测试应用。结果显示 ,在Na2 SO4 溶液中 ,羟基释放量明显受pH和SO2 - 4加入量的影响 ,羟基释放量的动态变化很好地符合Elovich方程。
By use of the hardware of MIA 3 autoanalytical system, we developed a special software according to the need of research, and set up an autotitration system which can be used in constant pH, and tried to apply it to the telease process of surface hydroxyl of a latosol with great iron oxidex. The results conform that the quantities of hydroxyl released are affected by pH and the amount of SO 2- 4added in Na 2SO 4 solution, and that the dynamic changes of hydroxyl release accord with Elovich equations.
