热重法(TG)是一种动态测量技术,可在程序升温或降温情况下对给定物质或体系提供一个连续的,以温度或时间为函数的重量变化曲线,所以由它跟踪反应能给出反应动力学的有关信息。这种非等温法与早期使用的等温法相比,有快速、连续和需要较少实验数据等优点,近年来在动力学研究方面得到广泛应用,但还只限于研究下列几种类型的简单 Thermogravimetry (TG) is a dynamic measurement technique that provides a continuous, weight-dependent curve of temperature or time as a function of temperature or time for a given substance or system under temperature programmed conditions so that the reaction can be followed The reaction kinetics of the relevant information. Compared with the isothermal method used earlier, this kind of non-isothermal method has the advantages of fast, continuous and less experimental data. It has been widely used in kinetic studies in recent years, but it is still limited to the following types of simple
