| Abstract: | In the paper, the mechanism and application of alkali mineral brucite and its calcined product in ozonation water treatment were summarized. The azo dye active brilliant red X-3B, nitrobenzene, aniline and phenol were chosen as samples, and the catalysis in presence of brucite and calcined product magnesia were investigated respectively. Based on these experimental results, the different catalysis mechanism of brucite and magnesia were proposed. Then, the ozonation theory was developed further and advice was given to rational application of alkali mineral. |
