Abstract
Low cost biosorbents containing 8-hydroxyquinoline functionality were fabricated in its natural (RI&R2) or magnetic (R3) forms. Removal
of AI(Ill) from aqueous solutions was studied using chemically modified
cellulose with 8-hydroxyquinoline through two different methods. Kinetic
studies indicate that the adsorption reaction follows the pseudo-second
order model and equilibrium adsorption was achieved within 60-10 min.
R2 with long spacer arm showed fast kinetics towards Al(III) removal if
compared with RI. Thermodynamic parameters obtained indicate that the
adsorption process is spontaneous and exothermic. The observed high
surface area of R3 (139.04 m2jg) may be explained by the proposed
formed stretched cellulose thin layer on the surface of magnetite particles.
High uptake capacity of R3 (2.8 mmol/g) at pH 2.5 may be explained to
proceed through interaction between the aquo-iron complexe with high
positive charge [Fe(H20)4(OH)2Fe(H20)4]4+ and the resin active sites
(nitrogen atoms along with 8-hydroxyquinoline moieties). The adsorption
process was found to fit well pseudo-second order model and possessed
an endothermic spontaneous nature. Selective and efficient adsorption of
Fe(Ill) from real samples made R3 resin applicable in the field of
Drinking water treatment.Fast and efficient adsorption of the investigated
metal ion indicates that its uptake from different drinking waters as a
harmful pollutant may be applicable in the applied field.
