| Abstract:Effects of four phase transfer catalysts including cetyltrimethyl ammonium bromide (CTAB), benzyl trimethyl ammonium chloride (TMBAC), tetramethyl ammonium chloride (TMAC) and manganese acetate on advanced treatment of mid-stage pulping effluent by potassium ferrate were studied. The results showed that the optimal pH value for the four phase transfer catalysts was 4. CTAB had obviously promoting role on treatment effect, CODCr removal efficiency achived more than 60% when CTAB and potassium ferrate dosages were 0.2 mg/L and 40 mg/L, respectively, and the reaction time was 20 min. When TMAC and potassium ferrate dosages were 0.6 mg/L and 40 mg/L, respectively and reaction time was 20 min, the higest CODCr removal efficiency of 49.3% was achived. While the higest CODCr removal efficiency of 58.4% was achived when TMBAC and potassium ferrate dosages were 0.2 mg/L and 60 mg/L, respectively , and the reaction time was 20 min. When manganese acetate and potassium ferrate dosages were 0.6 mg/L and 60 mg/L, respectively, the reaction time was 30 min, CODCr removal efficiency achieved the higest value of 56.4%. |
