Abstract

Oxidation of N,N-dimethylformamide(DMF) and N,N-dimethylacetamide(DMA) was investigated in a 30 liter semi-batch reactor. Five reaction processes were studied by using UV alone, O₃ alone, O₂/UV, O₂/O₃/UV and H2 O₂/UV respectively. Mathematical models have been developed to interpret the reaction kinetics. Reaction rate constants and mass transfer coefficients were determined by using Rosenbrock Hillclimb optimization algorithm. The experimental data and the predicted results from the models were compared. The kinetic parameters obtained from the previous semi-batch modes were applied to the continuous stirred tank reactor (CSTR) system. Results of this work show that the laboratory scale investigation using semi-batch reactor has great potential to develop the kinetic parameters required for the large scale CSTR system for the degradation of several aqueous pollutants.
