title: Kinetics of degradation by immobilized cells with ultrasonic irradiation.
abstract: Linear alkylbenzene sulphonate (LAS) decompositions by immobilized cells with ultrasonic irradiation were investigated at the optimized condition in order to gain insight into the kinetics of the decomposition process. Firstly, by analyzing the decomposition process of LAS theoretically, showed the kinetic model of suspending cells and immobilized cells both followed the MONOD model (namely micro=micromaxs/(ks+s) during wastewater treatment, then discussed the kinetics model of LAS degradation by immobilized cells with ultrasonic irradiation at the presupposition conditions, and then the two unknown parameters ([See text]) in the gained model were researched at the condition of laboratory. Moreover, experiments have been done to validate the parameters ([See text]) in the kinetics equation, the result shows the valid kinetics equation of LAS degradation is at the LAS concentration of 30-80 mg/L:
