الوصف: In this bio-analytical study, a fungal biomass Pleurotus eryngii was biologically produced, characterized and exploit to specifically adsorb Pb(II) ions from the water system. Characterization techniques such as Fourier transform infrared spectroscopy and atomic force microscopy were employed to characterize the pure and Pb(II) ions loaded biomass. Impact of different equilibrium parameters for the sorption of Pb(II) ions on P. eryngii was examined. The sorption process followed the Langmuir isotherm model with the calculated monolayer sorption capacity of 2.971 mg g−1 at temperature 303 K. The kinetic data illustrated well by the pseudo-second-order model. With the dynamic gathering of functionalities (–NH2, –NH–, –OH, and carboxyl), the sorption reaction occurred both inside and on the upper surface of biomass. This study revealed the potential of P. eryngii sorbent for the exclusion of Pb(II) ions from the water system.
