Exploring the biosorption of nickel and lead by Fusarium sp. biomass: kinetic, isotherm, and thermodynamic assessment.

Fungal biomass is as a cost-effective and sustainable biosorbent utilized in both active and inactive forms. This study investigated the efficacy of inactivated and dried biomass of Fusarium sp. in adsorbing Ni and Pb from aqueous solutions.

Cu, Cr, and Ni in mono- and multi-component aqueous solution adsorbed in passion fruit peels in natura and physicochemically modified: a comparative approach.

Among the low-cost adsorbent are agricultural residues, which can be used in natura or modified forms. This work evaluated the adsorption of Ni, Cu, and Cr in mono- and multi-component aqueous solutions using passion fruit peels in natura (Nat-PF) and physicochemically modified (Mod-PF). The adsorption was investigated by kinetic and isotherm models.

Activated carbons from passion fruit shells in adsorption of multimetal wastewater.

This work aims to use a solid agro-industrial residue (passion fruit shells-PF) to manufacture different activated carbons (ACs) capable to retain Cr, Cu, and Ni on synthetic wastewater. The PF was carbonized and chemically activated with three precursors, giving rise to three ACs: phosphoric acid ([Formula: see text]), sodium acetate ([Formula: see text]), and potassium hydroxide (AC). The ACs were characterized by SEM, ASAP, FTIR, and pH-PZC.
