Synthesis and adsorption properties of Chitosan cross linked with phenol - formaldehyde resin for the removal of heavy metals and dyes from water

A novel activated carbon material has been prepared by carbonization and activation of Phenol- Chitosan-Formaldehyde resin (PCFR) which synthesized by the condensation polymerization method. The physicochemical properties of the PCFR were characterized by SEM, XRD, BET, EDS, TGA and FTIR spectroscopy. The adsorption properties of Pb(II) ion and Methylene blue (MB) onto PCFR were investigated by batch techniques. The particle size of adsorbent was 65-70µ. Kinetic studies indicated that Pb(II) ion and MB adsorption followed the pseudo-second-order model. The adsorption may be controlled by external mass transfer followed by intra-particle diffusion mass transfer. Equilibrium adsorption was investigated by the Langmuir, Freundlich, Temkin, D-R and Jovanoic isotherms. The thermodynamics parameters of adsorption
