[ 1 ] - Photocatalytic degradation of methylene blue dye over immobilized ZnO nanoparticles: Optimization of calcination conditions

In the present study, calcination conditions during the synthesis of zinc oxide nanoparticles were optimized using response surface methodology (RSM) based on central composite design (CCD). After that, the effect of the type of UV irradiation on the photocatalysis of methylene blue (MB) dye was studied based on the kinetic model obtained at optimum conditions. Analysis of variance (ANOVA) exhi...

[ 2 ] - Comparison of the Effect of Perchlorine, Sodium Hypochlorite, and Electrochemical Method on Disinfection of Vegetables

Introduction: Many vegetables are eaten raw which can lead to the prevalence of food borne diseases if not properly sanitized. The aim of this study was to compare the effect of chlorine, bleach and multioxidant solution in disinfection of edible vegetables. Materials and Methods: In this experimental study, 100 g of vegetables (lettuce, basil and mint) was disinfected by sodium hypochlorite, ...
