FIELD: chemical industry and agriculture; production of hydrosol of ferric iron hydroxide.
SUBSTANCE: the invention is intended for a chemical industry, an agriculture and pedology and may be used at production of solutions for soils reclamation. 0.5 l of a ferric chloride solution with concentration of 0.5 l/mole gram-molecule is poured into a pan. Carbon electrodes are put into the solution. Pass a current of 1А. Each 5-60 seconds polarity of the electrodes is changed. In a result of replacement of anions of the salt for ions of the hydroxyl obtain a stable hydrosol of the ferric iron hydroxide. The invention allows to produce such sols using a simple and a production-friendly method commercially.
EFFECT: the invention allows to produce such sols using a simple and a production-friendly method commercially.
