Abstract

A mathematical analysis of the obtained experimental data was performed using topochemical equations in a linearized form: Kazeev–Erofeev–Kolmogorov, Ginstling–Brounshtein, Jander, and Gray–Weddington equations. It was found that the interaction mechanism of nepheline concentrate with sulfuric acid is most accurately described by the Ginstling–Brounshtein equation. The activation energy of the process was determined, based on which it was concluded that the process is controlled by kinetics.

霞石硫酸分解动力学研究

利用线性化形式的拓扑化学方程：Kazeev-Erofeev-Kolmogorov， ginstling - bronshtein， Jander和Gray-Weddington方程对获得的实验数据进行数学分析。研究发现，用ginstling - browshtein方程最准确地描述霞石精矿与硫酸的相互作用机理。测定了反应的活化能，得出反应受动力学控制的结论。
