Removal of Congo Red and Methyl Red using Low Density Polyethylene-Chitosan Nanoparticles Biocomposite in Single and Binary-component System

The low density polyethylene-chitosan nanoparticles (LDPE/CHNP) biocomposite was applied as a biosorbent for the adsorption of Congo red (CR) anionic dye and methyl (MR) cationic an in single binary system. effect parameter pH, contact time, initial concentration, adsorbent dosage temperature were studied on two dyes component Kinetic studies showed that LDPE/CHNP binary-component system follows pseudo-second order kinetics. values CR gotten to be 0.9996 0.9984 respectively, while MR 0.9994 0.9983 respectively. equilibrium study tested with both Langmuir Freundlich isotherm result they agree more have 0.9995 0.9991 0.9954 respectively; which implies adsorptions chemisorption than physiosorption reaction. In systems, reveals had higher adoption efficiency could because chelation between cations chitosan chains, decreased electrostatic interaction Methyl biocomposite. has proved efficient (anionic dye) (cationic two-component are frequently encountered composition industrial effluents.
