METHOD FOR RECEIVING NATURAL ZEOLITE MODIFIED WITH SILVER METAL

摘要

A method provides natural zeolite treatment with AgNO₃ solution and set in zeolite structure the Ag+ ions reduction by ion-exchanging until receiving silver metal by means of hydroquinone solution; at that regeneration of hydroquinone used in the process is executed with electrochemical reduction of formed quinone at the same process on an electrode, from carbonated felt of diaphragm electrolyzer, and in the result the quinone con¬centration is decreased down to 2.10-4 M, and hydro¬quinone concentration is increased up to 1, 10-2 M, at the same time cathodic current density is decreased from 50 to 3 a/m2.
