Structural And Morphological Properties Of (Ns. Bc/ Zno)Bio-Composite Adsorption

Abstract

Thesynthesis in a single step from charcoal nut shells (Ns) to obtained a novel Ns. Biochar/ ZnO bio-composite. The chemical activation of the Bio-carbon with a solution of ZnCl₂ at 0.136 mole and neutral pH to give a pure composite at T=600 °C which is characterized by scanning electron microscope(SEM), x ray diffraction(DRX) and spectroscopy Fourier transform-infrared (FTIR) and UV-Visible spectroscopy to studyadsorption of copper ions. The adsorption kinetic appropriate to the Experimental data is the pseudo-second order model kinetic. The experimental adsorption capacity for copper ions is 1273 mg/ gat temperature  20°C. Thus, the low-cost synthesis of the ZnO Bio-composite is a promoter axis for the adsorption of copperions.
