“…onto periwinkle shell activated carbon can be represented by a pseudo-second-order kinetic model which relies on the assumption that chemisorption may be the rate limiting step. In chemisorption, the metal ions stick to the adsorbent surface by forming a chemical (usually covalent) bond and finds sites that maximize their coordination number with the surface [43], Similar results of a second order kinetics was reported by [44] for the adsorption of copper from industrial waste waters by periwinkle shells activated carbon.…”

Iron (III) adsorption from aqueous solutions unto periwinkle shell carbon (PSC) was studied using batch experiments. Activated periwinkle shell carbon was prepared (pyrolysed at 300˚C and activated with nitric acid) and characterized to determine its physiochemical properties. Batch adsorption experiments were conducted to investigate the effects of process parameters (contact time, particle size, carbon dosage and pH of stock solution) on adsorption rate. Adsorption kinetics was tested using pseudo first and second order models. Adsorption Isotherms were analyzed using the Langmuir, Freundlich and Temkin isotherms while Thermodynamics parameters such as Enthalpy change (∆H˚), Entropy change (∆S˚) and Gibbs-free energy change (∆G˚) were determined. Results showed that adsorption rate increase with increase in contact time, adsorbent dose and pH and decreased with increase in particle size. Batch adsorption Kinetics experiments revealed that the mechanism of adsorption followed pseudo-second-order kinetic model. Isotherm data showed that the Langmuir isotherm accurately described the adsorption data indicating that adsorption process was mainly monolayer on a homogeneous adsorbent surface. Thermodynamic parameters results showed that adsorption process was endothermic with Enthalpy change (∆H˚): 222.91 kJ/mol; a positive Entropy change (∆S˚) of 19.19 kJ/mol, indicating an increase in the degree of freedom (or disorder) of the adsorbed species and a negative Gibb's free energy (∆G˚) at all temperature indicating that the adsorption process was spontaneous and favorable at high temperature.

This paper investigates the effect of use zinc chloride in varying impregnation ratios ranging between 0.1 and 1.5 to chemically activate carbonized periwinkle shells. Studies to characterize the activated carbon were conducted at ambient conditions. The experimental results revealed that the impregnation ratio at 1.0 gave the optimum values for parameters such as iodine number and porosity; and minimum values for parameters like pH and moisture content which represent properties for characterizing maximum adsorption. This study successfully demonstrates the potential of ZnCl2 can be used as an activating agent for producing high quality activated carbon which overall has the capacity to impact positively on the quality of the environment. @JASEM

“…4 Metallic effluents can lead to increased nutrient load in water bodies especially if they are essential metals. 5 Also, these metals in effluent may increase fertility of the sediment and water column and consequently lead to eutrophication, which in open waters can progressively lead to oxygen deficiency, algal bloom and death of aquatic life.…”

Contamination of environment by heavy metals has become a major concern worldwide. The role of conventional methods in remediating heavy metals has become ineffective and costly. Therefore, it becomes imperative to explore bioremediation using a cost effective, efficient and environmentally friendly alternative method of removing heavy metals. In this study, the adsorption behavior of Sorghum husk, a low-cost adsorbents, with respect to Pb +2 and Cd 2+ ions, has been studied in order to consider its application to the treatment of wastewater. The physicochemical properties of the unmodified sorghum husk were predetermined. The batch experimental method was employed: parameters such as pH, contact time, particle size and initial metal concentration were studied. The influence of the pH of the metal ion solutions on the uptake levels of the metal ions by the adsorbent used was carried out between pH 3 and 8. The optimum pH for Pb +2 and Cd +2 removals by sorghum husk were 6 and 5 respectively. An equilibrium time of 80min was required for the adsorption of Pb +2 and 60min for Cd +2 ions onto sorghum husk. Percentage sorption of Pb +2 increased from 21 to 80% and that of Cd +2 from 15 to 55% as adsorbent dose was increased from 0.1 to 1g while adsorption capacity decreased from 14 to 5.3mg/g for Pb +2 and 32.5 to 9.3mg/g for Cd +2 with increase in dose. Percentage removal of Pb +2 increased from 24.8 to 93.7% while that of Cd +2 from 22.4 to 91.6% with decrease in adsorbent particle size from 1000μm to 100μm. The uptake capacity of the adsorbent increased from 6.5 to 12.4mg/g for Pb +2 and 2.1 to 5.3mg/g for Cd +2 as the initial metal ion concentration was raised from 50 to 200mg/L. The experimental data was fitted into the Langmuir and Freundlich models; the data was best fitted with the Langmuir model. The results demonstrated that sorghum husk holds potential to remove cationic heavy metal species from industrial wastewater.Keywords: bioremediation, adsorption, wastewater, heavy metals, isotherms Journal of Applied Biotechnology & Bioengineering Research ArticleOpen Access Characterization and adsorption isotherm studies of Cd (II) and Pb (II) ions bioremediation from aqueous solution using unmodified sorghum husk 114Copyright: ©2017 Tatah et al.
