Exploring the potential of Juglans regia-derived activated carbon for the removal of adsorbed fungicide Ethaboxam from soils

The dearth of adsorption studies on aminothiazole carboxamide-based fungicide Ethaboxam has eventuated to its current investigation of sorption behavior on soil samples utilizing standard batch equilibrium method. Ethaboxam-based sorption studies have never been reported in the selected regions. Linear adsorption coefficient ( K d ) ranged from 3.2 to 16.74 μg mL −1 . The highest value of K d was observed for soil rich in organic matter. Low Gibbs free energy values indicated the weak interaction between soil particles and Ethaboxam resulting in physiosorption and an exothermic reaction. Statistical analysis expressed a negative correlation between soil pH and K d ( R 2 = − 0.85 and p
