Abstract
Organic Pesticides are toxic to humans on consumption if disposed with inefficient treatment facilities in water bodies or on land. The present study is aimed to investigate the removal of agricultural pesticides including three herbicides Trifluralin, Glyphosate and 2,4 Dichlorophenoxyacetic acid from aqueous solution by carbon nanoparticles synthesized from pomegranate. The synthesized nanoparticles provide high specific surface area, more capacity and faster uptake kinetics. nanoparticles have an average size of approximately 30-50 nm. Particle size distribution is equal and homogeneous and shows the good synthesis of nanoparticles with the same size. Various physico-chemical parameters such as pH (5-9), initial concentration (50-250 mg/L), and adsorbent dosage (0.1-0.5gr) level and equilibrium contact time (0-40 min) were studied. The results showed that removal of the agricultural pesticides Trifluralin, Glyphosate and 2,4D depends on pH such that the optimal removal efficiency observed for pesticides Trifluralin, Glyphosate and 2,4D in pH=9 was 92.6, 78 and 92% respectively. Optimal adsorbent weight was 0.5 g for pesticides Trifluralin, Glyphosate and 2,4D so that the removal efficiency was equal to 97, 98.8 and 98.4% within 20 minutes. In the initial concentration of 50 mg/L, the removal efficiency was respectively equal to 88, 94 and 92% for Trifluralin, Glyphosate and 2,4D.
