Abstract. The adsorption of Fe(II) from aqueous solutions by acid modified jackfruit wood sawdust biosorbent was investigated in a batch adsorption system. The experiment conducted at room temperature and pH 5 resulted adsorption behaviour of chemical modified Jackfruit wood sawdust biosorbent. The removal of Fe(II) has been found to be the function of initial Fe(II) concentration, acid type and acid concentration. The best removal was at low Fe(II) initial concentration, the higher initial concentration resulted on lower adsorption. Untreated jackfruit wood sawdust has the highest adsorption efficiency, followed by acetic acid, citric acid and tartaric acid modified jackfruit wood sawdust. The maximum uptake capacity of Fe (II) ion was 1.05 mg/g by untreated jackfruit wood sawdust.

“…The reason is the low level of porosity where progressively increasing amount of activation chemical takes place as more oxygen functional group is incorporated into the impregnated char samples. Moreover, R. Baccara and J. Bouzida [27] had proved that the surface area of the sorbent increases first rapidly (from 716 to 1020m 2 g −1 ) with an increase of acid concentration from 35 to 60% H 3 PO 4 , a concentration of 60% H 3 PO 4 seemed to be the most suitable for the development of a high specific surface area of the adsorbent material. Several researchers had established that in the case of H 3 PO 4 activation of other agricultural materials (woods, coconut shell, date pits, grain sorghum), temperatures neighbouring 45…”

Activated carbon derived from pine cones waste was prepared by carbonization at 450 • C, activated by different activating agents: ZnCl 2 , H 2 SO 4 and NaOH, and then pyrolyzed at 600 • C. Adsorption of Cr VI and other heavy metals (Mn II, Fe II, Cu II) on activated carbons was investigated to evaluate the adsorption properties. Special attention was paid to the effects of carbon surface functionalities that were analyzed by FT-IR and zeta potential study. Moreover, XRD study of activated carbon was also carried out. Results had shown that activated carbon by NaOH was the best adsorbent for removal of chromium VI from wastewater. The solid-solution interaction was determined by analyzing the adsorption isotherms at room temperature at different pH. When pH is above 4, the removal fraction of Cr (VI) ions decreased with the increase of pH. The removal fraction of Cr (VI) ions decreased below pH 4. The preferable removal of Cu (II) over Mn(II) and Fe (II) could be due to its lower affinity to solvent.Pseudo-second order equation provided the better correlation for the adsorption kinetics data. Equilibrium isotherms were determined by Fowler-Guggenheim model.

Abstract-Bottom ash is a waste material obtained from electricity generation through combustion of coal at the Mae Moh power plant in Thailand. The adsorption of Cd (II) and Zn (II) ions from aqueous solutions onto bottom ash was studied using batch experiments. The effect of pH, contact time and temperature were investigated. Adsorption isotherm data for metal ions was analyzed by the Langmuir and Freundlich isotherms. The Freundlich isotherm properly described the adsorption data for all studied temperatures. The results revealed that the adsorption kinetics followed pseudo-second-order kinetic model. Thermodynamic parameters such as Gibbs free energy change (∆G°), enthalpy change (∆H°) and entropy change (∆S°) were investigated. The calculated values showed that the adsorption process for both Cd (II) and Zn (II) ions was endothermic.
