Eco-friend shellfish powder of the mussel Brachidontes variabilis for uptake lead (II) ions

Abstract This study aims to employ clam powder as an environmentally acceptable sorbent capture lead(II) from aquatic media. Mussel Brachidontes variabilis “ Mytilus arabicus ” shells collected the intertidal zone of Gulf Suez for producing shellfish (SFP). Before and after lead loading, SFP was characterized using X-ray fluorescence (XRF), Fourier transform infrared (FT-IR) spectra, transmission electron microscope (TEM), scanning (SEM) equipped with energy dispersive (EDS), diffraction (XRD). Maximum Pb(II) ion removal capacity done a function shacking duration interval, particle size, pH, Pb (II) concentration, dose, temperature, agitation rate. Numerous mathematical kinetic isothermal approaches were used equilibrium experimental data validate highest bio-sorption capabilities (in mg g -1 ). Optimal conditions determined be 90 min, 0.063 mm pH 5.5, 130 L ions in 50 mL solution, 0.05 SFP, 25 o C, 250 rpm. In this sorption process, Qasi-1 st order monolayer Langmuir simulations prominent. terms thermodynamics, capturing by spontaneous (− ΔG ), endothermic (+ ΔH highly disordered at interface phases ΔS addition, well uptake effluents wastewater various water matrices.
