METHOD OF PRODUCTION OF HYDROSOLS OF SILICIC AND HUMIC ACIDS FROM ALKALINE SOLUTIONS OF THEIR SALTS Russian patent published in 2005 - IPC

FIELD: chemical industry; agriculture and pedology.

SUBSTANCE: the invention is dealt with the fields of chemical industry, agriculture and pedology, in particular, with methods of production of solutions for soil melioration. The method provides for substitution of cations of salts in a water solution for hydrogen ions by ionic exchange. The process of the ionic exchange is carried out between a container with a saline solution and containers with solutions of an acid contacting among themselves through the cation-exchange membranes. The process of the ion exchange is intensified by electrolysis at electrodes placement in the containers with acids. Polarities of the electrodes are switched over in each 5-60 seconds. The method ensures production an electrolysis stable hydrosols of silicic and humic acids and their mixes commercially.

EFFECT: the invention ensures production of stable hydrosols of silicic and humic acids and their mixes commercially.
