The Ability of Edible Fungi Residue to Remove Lead in Wastewater

Lead (Pb)-contaminated wastewater is the most common source of heavy metal ion pollution. In this study, agricultural waste edible fungi residue (EFR) was used to adsorb Pb(II) ions in as a strategy reduce environmental pollution and minimize poisoning by Pb. The influence concentration, solution pH, EFR concentration on removal efficiency (R) investigated with single factor design response surface analysis. maximum predicted R for 76.34% under optimal conditions 483.83 mg/L, 4.99 g/L, pH 5.89. actual experimental value reached 76.97% these conditions. competition available adsorption sites limited R. A comparison Fourier transform infrared spectroscopy before after Pb(II), indicated that functional groups significantly affected effect metals, process primarily range wavenumbers from 500 2,000 cm ?1 .
