Abstract:

Kinetics of 4-aminobenzenesulphonate(4-ABS) degradation by Pannonibacter sp.W1 under aerobic condition was studied. At medium and low initial concentration (50-1?000 mg/L ),the 4-ABS could be degraded almost completely in 14 h,and the degradation reaction conformed to one order kinetics. At high initial concentration (1?200 -2?500 mg/L ),up to 90% degradation rate could be achieved in 32 h,and it conformed to zero order kinetics in earlier period of degradation and one order kinetics in later period of degr...
