“…The AOP technique has drawn considerable attention from various quarters of scientific community as it is easy to handle and produces significantly less residuals as compared to the classical approaches. Amongst the many techniques employed in the AOP approach are the UV photolytic technique [15,16], Fenton process [17,18], photo-Fenton process [19,20], ozonation process [21], sonolysis [22,23], photocatalytic approach [24,25], biodegradation [26,27] and the radiation induced degradation of dyes [28,29].…”

The nanophotocatalytic process using semiconducting oxides with a nanostructure is one of the technologies used for the destructive oxidation of organic compounds such as dyes. The photocatalytic oxidation of a textile dye-C. I. Basic Blue 41 (BB41) in aqueous solution was assessed by UV ray irradiation in the presence of TiO 2 nanoparticles. The effect of initial dye concentration, pH and TiO 2 loading were investigated and the optimized conditions for maximum amount of degradation were determined. Analysis of the kinetics showed pseudo-first-order model. The mineralization of the dye was reported by measuring the initial and final chemical oxygen demand of the solution that was irradiated under optimized conditions.

“…Tong Han et al 59 used a UV irradiated photo catalytic reactor and nanoTiO 2 catalyst to decompose acephate insecticide from water. Mohamed et al 60 used gamma radiation to decompose diazinon and atrazine in water solution. Pei et al 61 studied the sorption process of 2,4,6‐trichlorophenol in order to the lead effects.…”

Worldwide pesticide usage has increased dramatically during the last three decades, coinciding with changing practices and increasing by intensive agriculture. This widespread use of pesticides for agricultural and non‐agricultural purposes has resulted in the presence of their residues in various environmental matrices. The occurrence of pesticides and their metabolite transported in rivers, channels, lakes, sea, air, soils, groundwater, and even drinking water, proves the high risk of these chemicals to human health and the environment. Therefore, pesticide removal is of an increasing concern. In this study, a review of the published literature dealing with pesticides removal process is presented. Firstly, pesticide removal by conventional means is briefly considered. Secondly, the use of the low‐cost sorbent through biosorption process is discussed comprehensively. The effect of factors such as pH, contact time, sorbent dosage, initial pesticide concentration, and optimization of biosorption conditions is also discussed. Kinetic, thermodynamic, and mechanism studies are also given. This study shows that both microorganisms and other materials with biological origin like agricultural by‐products may be used to this end. There is a significant potential for pesticide uptake by the use of various pristine and especially modified biosorbents. In the case of living organisms used as removal agents, degradation may also play a role in the total removal observed.

“…The published report shows the presence of diazinon in Saudi soil as high as 0.024 mg/kg (Al-Wabel et al, 2011). Its concentration in natural groundwater is reported to range from 0.32 to 3.286 µM (Mohamed et al, 2009). The concentrations (0.002-0.03 µg/kg of wet weight) of diazinon in the muscles of different fish cultured in Riyadh region were reported by El-Saeid (2010).…”
