Abstract: 

Simultaneous presence of heavy metal and organic compound (like phenol and cadmium), is one of the most important environment pollutant source that there are in petrochemical industrial, plating and etc, that have adverse effects on environment and human health. Therefore, the purpose of this study is, photocatalytic removal of cadmium with UV/ZnO process in presence and absence of phenol and formate as hole scavenger from aqoues solution in batch system. First, design and construction of reactor was done. To the study on role of adsorption process, solution was equilibrium in dark for 30 minute. Then effect of various parameters was investigated in the presence of UV light. So optimum pH was obtained with chang solution pH and constant conditions. After clarifing optimum pH, the effect of nanoparticle dosage, concentration of cadmium, contact time and effect of presence and absence of phenol and formate was investigated. Although removal of cadmium increased with increase of pH, but to preservation of cadmium in the solution form, in experiment pH was 7. Removal efficiency increased with increase of contact time and optimum dosage was obtained equal to 2 g/L. Too photocatalytic removal efficiency was decreased with increase of initial cadmium concentration. Also the obtained results showed that presence of phenol and formate cause increase of cadmium removal efficiency. Generally the result of this study showed that studied methodology can be used as a effective method in photocatalytic removal of cadmium with UV/ZnO process in presence of phenol and formate as hole scavenger.
