Preparation, Characterisation And Adsorption Properties Of Chitosan And Chitosan Derivatives Beads For The Removal Of Copper(Ii) And Lead(Ii) Ions
In this study, a batch adsorption system was applied to study the adsorption of copper(II) and lead(II) ions onto chitosan, chitosan-glutaraldehyde (GLA) (1:1 and 1:2), chitosan-alginate and chitosan-tripolyphosphate (TPP) beads. The physicochemical properties of all five adsorbents were analysed...

| الملخص: | In this study, a batch adsorption system was applied to study the adsorption of
copper(II) and lead(II) ions onto chitosan, chitosan-glutaraldehyde (GLA) (1:1 and
1:2), chitosan-alginate and chitosan-tripolyphosphate (TPP) beads. The
physicochemical properties of all five adsorbents were analysed based on infrared
spectroscopy, light metal cations analysis, surface area and pore size analysis, CHN
analysis and X-ray diffraction analysis. Different parameters affecting the adsorption
capacity such as initial pH, agitation period, agitation rate, particle sizes, adsorbent
dosage, initial concentration of metal ions and temperature were studied. Adsorption
isotherm data for copper(II) and lead(II) ions onto all five adsorbents were
determined and correlated with Langmuir, Freundlich, Dubinin-Radushkevich (D-R),
Sips and Redlich-Peterson (R-P) isotherm models. |
