Abstract:
Objective To investigate the catalysis of Co - Cu /SiO2 in oxidation of sodium percarbonate (SPC ) for o-nitrochlorobenzene. Methods The solution of o-nitrochlorobenzene was prepared, acetic acid was used to adjust acidity, sodium percarbonate was applied as the oxidant, the self-prepared Co-Cu/SiO2 was used as the catalyzer to catalyze the degradation reaction of o-nitrochlorobenzene and the effect of reaction condition on degradation was researched. Results In the condition of loading amount of metal was 5%, nCo:nCu= 4:1,nCo-Cu=1.90?10-3mol,nSPC=6.36?10-3 mol,cOCNB=50 mg/L and t=80 ℃,pH=4,the degradation efficiency of o-nitrochlorobenzen could reach 92% . Conclusion Co-Cu/SiO2 is efficient in catalyzing the oxidative degradation of sodium percarbonate for o-nitrochlorobenzene and is applicable to the waste water treatment for eliminating o-nitrochlorobenzene
