| Abstract |
| The photocatalytic degradation of the Chlorpyrifos Pesticide (CPF) was assessed using a static mixer reactor with immobilized Cu2(OH)PO4- HKUST-1 MOF composite (CPH-MOF) visible-light-driven photocatalyst. This reactor employs the energy of the flow stream to produce consistent and reliable mixing, promoting the diffusion of CPF/CPH-MOF from the bulk liquid through a boundary layer to reach the liquid-catalyst interface and also the inter-particle diffusion of CPF/CPH-MOF within the catalyst film to the active surface sites. Under this condition, both external and internal mass transfer are improved, while an appropriate light distribution was provided to supply photon energy to activation of CPH-MOF. The influence of operational parameters including the initial concentration of CPF, irradiation time and pH on the process performance was studied and optimized through the desirability function approach which result indicated that designed system has excellent efficiency (%.99.84) under optimized conditions, set as 40 mg/L of the initial concentration of CPF, 60 min of irradiation time and 3 of pH. |
