A METHOD FOR THE SYNTHESIS OF A BIVALENT TIN OXY-HYDROXIDE ADSORBENT FOR THE REMOVAL OF HEXAVALENT CHROMIUM FROM WATER, PARTICULARLY DRINKING WATER, THE ADSORBENT AND ITS USE

摘要

The present invention refers to a method for the synthesis of an adsorbent which is realized by the production of a bivalent tin oxy-hydroxide [SnxOy(OH)z], with 1x6, 0y4 and 0z4, into a two-stage continuous flow reactor and a pH range 2-12. The material can be applied for the removal of hexavalent chromium, bromate, chlorate and perchlorate ions in drinking water treatment units for house, municipal and industrial use. The invention also relates to its adsorbent, resp. the use thereof.
