KINETIC RESEARCH AND MATHEMATICAL PLANNING ON THE OBTAINING OF POTASSIUM HUMATE FROM BROWN COAL OF THE LENGER DEPOSIT

This article provides information about the method of obtaining potassium humate obtaining from brown coal of the Lenger deposit, and also describes the elemental and mineralogical composition of potassium humate determined with SEM (JSM-6490l V, Jeol). Kinetic data on the decomposition of brown coal with solutions of potassium hydroxide are presented. The area of chemical reactions and the activation energy is determined. To determine the accuracy of the process of obtaining potassium humate from Lenger coal waste with the accuracy of experimental data, methods of mathematical planning were used, quadratic functions were established. The advantage of obtaining potassium humate is that they are environmentally safe and have high bioactivity. They are also characterized by a high content of humic substances that are involved in the structure formation of the soil, accelerate biochemical processes, and increase the physical and chemical characteristics in the soil. Under the influence of humate-containing substances, the function of microflora elements in the soil is activated, and the number of beneficial microorganisms increases.
