Title
Catalytic ozonation of azo dye active brilliant red X-3B in water with natural mineral brucite
Abstract

Natural mineral brucite was used directly in catalytic ozonation of dye wastewater of active brilliant red X-3B. Compared with single ozonation, degradation of X-3B increased from 47% to 89%, and removal rate of COD increased from 9% to 32.5% in catalytic ozonation for 15 min. The catalytic ozonation of X-3B followed a direct oxidization mechanism by ozone molecule, and this was actually a homogeneous catalysis of OH− due to dissolution of Mg(OH)2 from natural brucite. As a natural mineral catalyst, brucite has supplied an economical and feasible choice for catalytic ozonation of X-3B in industrial wastewater.
