Abstract:
In this work, perlite was used as a low-cost source of Si and Al in the synthesis of sodalite zeolite using hydrothermal synthesis method. Cu2O nanoparticles were coated on a bed of sodalite zeolite and used as an adsorbent for removal of diazinon from aqueous solutions. To analyze the process, a significant variable .i.e. removal efficiency (%) of diazinon and three dependent parameters as the process responses were examined through a central composite design (CCD) under the response surface methodology (RSM). The optimum conditions included: 0.22 g adsorbent, 23.62 min contact time, at 29.28 oC. The percentage removal of diazinon in batch administrations was 97.24.
