The presence of EDTA in wastewaters originating from photovoltaic (PV) process may cause significant environmental impacts. The aim of this work was the treatment of the effluents. resulting from the baths of the PV process. by a photocatalytic process based on TiO2 silver doped (Ag-TiO2) and using synthetic solutions containing EDTA. https://www.ngetikin.com/
