Abstract

Adsorption kinetic study provides understanding into reaction rate and mechanism of sorption during adsorption process. This research investigated the adsorption kinetics of the removal of Pb²⁺, Cr⁶⁺, Zn²⁺ and Fe³⁺ in aqueous solution using unmodified and oxalic acid modified cassava peel waste powder (CPP) using standard methods. Data obtained for the effect of agitation time revealed that within 30-60 minutes, both the unmodified and oxalic acid modified cassava peel powder (CPP) were able to remove 94% Pb²⁺, 80% Cr⁶⁺, 96% Zn²⁺ and 82% Fe³⁺ respectively. The experimental data were evaluated in terms of intra-particle diffusion coefficient and rate of adsorption, thus comparing transport mechanism and sorption process and found it to be 7.55 ± 0.05 mg/g for Pb²⁺, 6.4 mg/g and 6.39 ± 0.05 mg/g for Cr⁶⁺, 7.32 mg/g and 7.45 ± 0.01 mg/g for Zn²⁺, 6.74 mg/g and 6.48 ± 0.12 mg/g for unmodified and differentially modified respectively. Results from the experiment shows that the pseudo-second order model appropriately describes the kinetic process which supports chemisorption (R² > 0.99) value. There was no significant effect on removal by oxalic acid modification. The result further revealed that cassava peel powder can remove heavy metal ions from solution and this can be applied in waste water treatment operations.

This research investigated the adsorption kinetics of the removal of Pb2+, Cr6+, Zn2+ and Fe3+ in aqueous solution using unmodified and oxalic acid modified cassava peel waste powder (CPP) using standard methods. Data obtained for the effect of agitation time revealed that within 30-60 minutes, both the unmodified and oxalic acid modified cassava peel powder (CPP) were able to remove 94% Pb2+, 80% Cr6+, 96% Zn2+ and 82% Fe3+ respectively. The experimental data were evaluated in terms of intra-particle diffusion coefficient and rate of adsorption, thus comparing transport mechanism and sorption process and found it to be 7.55 ± 0.05 mg/g for Pb2+, 6.4 mg/g and 6.39 ± 0.05 mg/g for Cr6+, 7.32 mg/g and 7.45 ± 0.01 mg/g for Zn2+, 6.74 mg/g and 6.48 ± 0.12 mg/g for unmodified and differentially modified respectively. Results from the experiment shows that the pseudo-second order model appropriately describes the kinetic process which supports chemisorption (R2 > 0.99) value. There was no significant effect on removal by oxalic acid modification. The result further revealed that cassava peel powder can remove heavy metal ions from solution and this can be applied in waste water treatment operations.},

AB  - Adsorption kinetic study provides understanding into reaction rate and mechanism of sorption during adsorption process. This research investigated the adsorption kinetics of the removal of Pb2+, Cr6+, Zn2+ and Fe3+ in aqueous solution using unmodified and oxalic acid modified cassava peel waste powder (CPP) using standard methods.
