What is it about?
Various contaminants is continuously being released into the environment due to the expensive nature of the existing conventional methods of wastewater treatment. In this work, we prepared two materials from agricultural waste and applied them for the removal of a toxic metal from aqueous media.
Why is it important?
This work is important based on the following:
Perspectives- How have you benefited from the research?
I better understood the behavior of copper in various solution media. The adsorbents surface chemistry and morphology were better understood.
Low cost adsorbents prepared from the epicarp of Raphia hookeri fruit were used for the removal of copper (II) ion from aqueous solution. The effects of operational parameters such as pH, concentration and contact time, dosage as well as interference of other ions were studied. Optimum pH for raw and modified biomass were 5.0 and 5.5 with percentage removal of 75.08 % and 95.62 % respectively. Concentration of competing ions greatly reduced Cu2+ removal with both adsorbents while agitation speed had negligible effect on Cu2+ uptake. Adsorbents surfaces were activated as temperature increased thus enhancing adsorbent adsorption capacity at high temperature. Adsorption kinetic data fitted best into the pseudo second order model while the thermodynamics studies confirmed adsorption spontaneity and feasibility. The Freundlich adsorption isotherm best described the adsorption process and the Langmuir maximum monolayer adsorption capacity
for the raw (RHE) and acid treated (ARHE) biomass were 81.97 and 103.09 mg/g respectively. Chemisorption predominate the Cu2+-ARHE system hence desorption efficiency was obtained to be 72.65% with CH3COOH as eluent.
