Phosphoric acid-activated biochars from orange and potato peels as adsorption barriers to prevent picloram and imidacloprid leaching in contaminated soils
Abstract
values by 8 (picloram) and 120-fold (imidacloprid). In soil column experiments (100 g), the addition of a low-dose biochar barrier (20 mg for imidacloprid and 100 mg for picloram, mixed with 1 g of soil) effectively limited leaching to 12-24% and 25-30%, respectively, depending on the soil type. Overall, these results demonstrate that biochar derived from agricultural waste is an effective and sustainable amendment for pesticides immobilization, providing a promising strategy for mitigating soil and groundwater pollution.
