Degradation of toluidine blue by UV / H_2O_2 / ammonium ferric oxalate
The study used UV, H2O2, and ferric ammonium oxalate system to treat the degradation of Toluidineblue (113) solution. The effects of initial TB concentration, initial pH value, H2O2 concentration, and ferric ammonium oxalate concentration on the degradation rate of TB were investigated. The test results show that acidic conditions are conducive to the degradation of 11B, and its optimal degradation pH is 4.0. In the UV / H2O2 system, when the H2O2 concentration is 100 mmol / L, the TB degradation rate is relatively high; in the UV / H2O2 system, the TB degradation rate is higher when the ferric ammonium oxalate concentration is 10.0 mmol / L; compared to other System, the degradation effect of UV / H2O2 / oxalate ferric ammonium ferrate system is the best, and the degradation rate can reach 88.62%.
