Abstract

2,4-Dichlorophenoxyacetic acid (2,4-D), is one of the most commonly herbicides used in agricultural farms to control weeds. Accumulation of 2,4-D in natural water stream constitutes a serious issue because of the adverse effects on human and animal health. This study aimed to monitor and treat 2,4-D in different water resources in Egypt. Treatment obtained by zinc ferrite nanoparticles (ZnFe2O4) which prepared by sol–gel combustion method. The batch experiments were carried out to study the optimum removal conditions such as pH, dose, 2,4-D initial concentration, contact time, ionic strength and temperature. Results recorded tentatively the presence of 2,4-D in the Rosita River Nile and agriculture drainage channels with concentrations ranged from 0.35 to 21.31 μg L-1 using LC/MS/MS analyzer. The optimization study showed a maximum percent of removal is 97.84% for adsorption followed by photodegradation using 0.3 g of zinc ferrite nanoparticles for 15 min. at pH 8.0. Adsorption capacity was 0.34 mg/g at initial concentration (Co) 10 mg/L after 15 min. Pseudo-second order model is well fitted with the experimental data with a correlation coefficient 0.999. Adsorption is proceeded with Freundlich isotherm model with correlation coefficient 0.986. According to the study findings zinc ferrite nanoparticle was considered as a new novel solution for removing that hazard material
