СЕДИМЕНТАЦИОННЫЕ ХАРАКТЕРИСТИКИ ЭЛЕКТРОРАЗРЯДНЫХ ГИДРОКСИДОВ АЛЮМИНИЯ И ЖЕЛЕЗА

Аннотация

The properties of electrical discharge aluminium hydroxide and iron hydroxide have been investigated. On the basic of sedimentation technique the particle size of these materials was calculated. It was shown that the radius of particles depends on conditions of obtaining of the coagulants. Thus, the pres- ence of copper, chromium and zinc salts in water solution results in increasing of the radii particles of the materials. Besides, the sedimentation behavior of the coagulants is also changed. Obtained facts have to be taken into account at the development of the processes of purification of galvanic pollution by the electric discharge coagulant method.
