“…The percentage adsorbed remain fairly constant even at increasing adsorbent dosage could be attributed to small concentration of metal ions remaining in solution available for biosorption and exhaustion of the adsorbents as seen in Figure 1. Similar results have been reported (Choudhury et al, 2012;Nameni et al, 2008;Elaigwu et al, 2010;. Saueprasearsit et al, (2010), reported that increasing adsorbent dose increases amount adsorbed but decreases adsorption density.…”

ABSTRACT:The potentials of cocoa pod husk to adsorb Cu (II), Cd (II), Pb (II) and Fe (II) ions from aqueous solutions was investigated in a batch system. The effects of contact time, initial metal ion concentration and adsorbent dose on the adsorption capacity of the adsorbent were examined. The percent adsorbed increased as initial metal ion concentration, contact time and adsorbent dose was increased until equilibrium was reached. Langmuir isotherm and pseudo-second order models were used to analyse the equilibrium and kinetic experimental data respectively. Equilibrium experimental data of Cu (II), Cd (II), Pb (II) and Fe (II) adsorption onto cocoa pod fitted well to Langmuir model and the kinetic data also fitted well to the pseudo-second order model, as indicated by the correlation coefficients. The maximum sorption capacity (qmax) ranged as 4.16, 4.42, 4.69 and 4.83 mg/g for Fe (II), Cd (II), Cu (II) and Pb (II) respectively. This study demonstrated that the waste cocoa pod could be used as a potential adsorbent for toxic metals such as Cu (II), Cd (II), Pb (II) and Fe (II).

“…The effects of contaminated soil on seedling growth performance of T. indica are found mostly dependent on the concentration of automobile polluted soil treatment. A similar findings on gradual reduction in shoot length, chlorophyll and protein levels of Amaranthus hybridus L. with spent oil was observed by researchers (Odjegba and Sadiq, 2002;Elaigwu, et al, 2009). Germination and seedling establishment are vulnerable stages in the plant life cycle (Vange et al, 2004).…”

“…Further shaking after the equilibrium time, only result in desorption (Anwar et al 2010). This corresponds to the observation made by Elaigwu et al (2009). Table 3 shows the effect of temperature on removal of heavy metals: Copper, Nickel, Lead, and Cadmium.…”

This study details the removal of heavy metals; Cadmium, Copper, Nickel, and Lead from wastewater effluent using an activated carbon produced from African palm fruit. The effluent was obtained from Old Panteka market; a metal scrap Market located in Kaduna State, Nigeria, which has several components that constitute high level of pollution in the environment. The effect of temperature and contact time on the removal of these heavy metals using the activated carbon produced was investigated. The activated carbon showed a significant ability in removing heavy metals; Cadmium, Copper, Nickel, and Lead from the wastewater. Higher percentage removal was observed at a temperature of 80°C (93.23 ± 0.035, 96.71 ± 0.097, 92.01 ± 0.018, and 95.42 ± 0.067 % for Cadmium, Copper, Nickel, and Lead, respectively) and at an optimum contact time of 60 min (99.235 ± 0.148, 96.711 ± 0.083, 95.34 ± 0.015, and 97.750 ± 0.166 % for Cadmium, Copper, Nickel, and Lead, respectively) after which the percentage removal decreases. This work, therefore, suggests that African palm fruit can be successfully applied to solve this environmental pollution.
