The catalytic effect of tungstophosphoric solid acid H3PW12O40·6H2O on enzymatic hydrolysis lignin oxidation degradation was investigated in the presence of hydrogen peroxide. Judged from the spectra of FT-IR and UV, enzymatic hydrolysis lignin was degraded obviously by the solid acid catalyst. In reaction, the factors of catalytic effect were investigated on reaction time, dosage of tungstophosphoric...
To improve the safety of sewage recycle, The catalytic ozonation mechanism and oxidation kinetics of fulvic acid and nonylphenol ethoxylates (NPnEO) were studied using TiO2/AC /Iron as a catalyst of catalytic oxidation. The results show that: compared with the ozone oxidation alone, the removal of organisms in catalytic ozonation was higher, after the reaction 20min, the removal of COD in fulvic acid...
