Lithospherically sorbed cyclodiene insecticide sustainable remediation via green adsorbent derived from Arachis hypogaea shells

Résumé fourni par la source

The current investigation has attempted to investigate the adsorption pattern of a persistent organochlorine insecticide, Endosulfan via the standard batch equilibrium method. Results for the model application are expressed adsorption co-efficient Kd ranging from 0.7 to 10 µg/mL. Existence of physisorption was confirmed through an exothermic and low interaction between Endosulfan and soil samples are shown via Gibbs free energy (ΔG) with negative values. Statistical significance of the results was shown by negative association between soil pH and Kd (R2 = −0.74 and p = 0.01), while organic matter and adsorption were related to one another in a positive manner (R2 = 0.92). Additionally, statistical significance of the results was also expressed by ANOVA analysis results, indicating a p value of <0.05. In the sub-sequential manner, activated peanut shells powder, as a green adsorbent, has been used for Endosulfan pesticide removal from the selected soil samples. Activated peanut shells powder was exposed to the FT-IR analysis showing presence and augmentation of different groups. Endosulfan maximum removal was observed in 5 ppm concentration to be 78%, while in 7.5 ppm, it was 70%. Currently devised method can be efficiently used in a cost-effective manner for the removal of obnoxious pesticides from environmental compartments.
