Biochar Derived from Pineapple Leaf Non-Fibrous Materials and Its Adsorption Capability for Pesticides

Non-fibrous materials (NFMs) are typically discarded during pineapple leaf fiber processing. The underutilized NFM waste was proposed for use in this work as a raw material the production of biochar . removal pesticides (acetamiprid, imidacloprid, or methomyl) from water then investigated using derived (NFMBC). pseudo-second-order kinetic data suggested chemisorption pesticide on NFMBC. While acetamiprid imidacloprid adsorption NFMBC occurred primarily via multi-layered (best fitted with Freundlich isotherms), Sips isotherms matched experimental data, implying heterogeneous methomyl surface. capacities acetamiprid, methomyl, and 82.18, 36.16, 28.98 mg g–1, respectively, which agreement order polarity (low to high) pesticides. Adsorption indicated that preferably removed low-polarity sources. Since leaves provide fibers NFMs development, study should promote an extended agro-waste utilization approach full-cycle resource management fields.
