摘要

在建立新的化学溶解模型的基础上，对修正的V.V. Dolivo-Dobrovolsky方程得到的动力学参数进行了分析。结果表明，从一种矿物到另一种矿物的过渡过程中，参数的变化受到补偿效应的影响。此外，根据新的溶蚀模型进行计算，可以区分溶蚀过程中相同性质的矿物的整体性质和个别性质。这些矿物因活性表面配合物的浓度不同而彼此不同，并通过单一的透射系数和相同的活性配合物寿命值组合成一个系统。

A New Model of Chemical Dissolution of Solids: an Analysis of the Mechanism of Dissolution of Monodispersed Materials

On the basis of a new model of chemical dissolution, an analysis of the kinetic parameters obtained using the modified V.V. Dolivo-Dobrovolsky equation was carried out. It shows that the change in parameters during the transition from one mineral to another is subject to a compensation effect. Additionally, calculations based on the new dissolution model made it possible to distinguish between the systemic and individual properties of minerals of the same nature in the process of dissolution. These minerals differ from each other by the concentration of ac tive surface complexes, and are combined into a system by a single transmission coefficient and the same value of the lifetime of the active complex.
