A novel co-catalyzed system between persulfate and chlorite by sonolysis for removing triphenylmethane derivative
文献摘要：
Triphenylmethane (tpm) derivatives (e.g.tpmcv) have threatened the safety of the aquatic environment due to the potential toxicity and carcinogenicity.In this study,the novel ul-trasonic/persulfate/chlorite (US/S2O82-/ClO2-) oxidation process was developed for the ef-fective removal of tpmcv in wastewater.The apparent non-integer kinetics (n around 1.20)of tpmcv degradation under different factors (R2Adj ＞ 0.990) were investigated,respectively.Inhibiting effects of anions were greater than those of cations (except Fe(Ⅱ/Ⅲ)).The adding of micromolecule organic acids could regulate degradation towards positive direction.The double response surface methodology (RSM) was designed to optimize tpmcv removal pro-cess,and the acoustic-piezoelectric interaction was simulated to determine the propagation process of acoustic wave in the reactor.The possible degradation pathway was explored to mainly include carbonylation,carboxylation,and demethylation.The estimated effective-mean temperature at the bubble-water interface was calculated from 721 to 566 K after introducing the ClO2-,however,the adsorption or partitioning capacity of tpmcv in the reac-tive zone was widened from 0.0218 to 0.0982.The proposed co-catalysis of US/S2O82-/ClO2-was based on the determined active species mainly including ClO2,SO4·-,and · OH.Com-pared with other US-based processes,the operating cost (3.97 $/m3) of US/S2 O82-/ClO2-with the EE/O value (16.8 kWh/m3) was relatively reduced.
