Abstract
A system for removing organophosphateinsecticides was designed using modified bentonite and a finemicro-nanobubble generator. The native bentonite wasmodified with berberine chloride and MgO to form a berberinechloride/MgO composite powder, which was then used tofabricate ceramic porous balls approximately 2.0 cm indiameter and weighed around 7.2 g, with a permeability ofapproximately 1.5 × 10⁶ mD. Micro-nanobubbles weregenerated with mean and mode sizes of 193.9 ± 13.7 nm and107.7 ± 2.3 nm, respectively. The density of micro-nanobubbleswas approximately 7 × 10⁸/mL ± 1 × 10⁷. To evaluate the system'seffectiveness, tap water was spiked with 5 ppm of eachorganophosphate insecticide: methyl parathion, chlorpyrifos,profenofos, and dimethoate. The contaminated water was thenpassed through a filter composed of the modified bentoniteceramic balls. The concentration of each insecticide in the watertank was analyzed over time at 6, 12, 18, and 24-hour intervalsusing high-performance liquid chromatography. The resultsrevealed a linear decrease in insecticide concentrations overtime whereas chlorpyrifos was reduced at 15%, 32%, 40%, and42%, methyl parathion was at 10%, 25%, 30%, and 38%,profenofos was at 18%, 35%, 40%, and 45% and dimethoatewas at 8%, 20%, 30%, and 30% after 6, 12, 18, and 24 hours,respectively. The hybrid system demonstrated an ability toabsorb organophosphate insecticides, suggesting its potentialapplication for reducing insecticide residues in contaminatedwater zones, particularly in agricultural areas.
