Sorption of Cu(II), Zn(II) and Ni(II) from aqueous solution using activated carbon prepared from olive stone waste
The performance of olive stone activated carbon (OSAC) for sorption of Cu2+, Zn2+ and Ni2+ ions was investigated via batch technique. OSAC materials were prepared under different physially activation conditions. Olive stone waste was physically activated with N2 gas and steam gas at 900oC at 3.5h hold time (OSAC-3) was choice as the best one for Cu2+, Zn2+ and Ni2+ removal. Characterization for...
متن کاملSorption of dye from aqueous solution by peat
The sorption of two dyes, namely, Basic BIue 69 and Acid Bhre 25 onto peat has been studied in terms of pseudo-second order and first order mechanisms for chemical sorption as vrell as an intraparticle diffusion mechani!jm process. The batch sorption process, based on the assumption of a pseudo-second order mechanism, has been developed to predict the rite constant of sorption. the equ~lib~um c...
متن کاملReactive Dye Removal from Aqueous Solution by Sorption
* E-mail: [email protected] ABSTRACT Effluents of textile dyeing are characterized by intense colour, chemical oxygen demand, suspended solids and a variety of refractory matter, such as heavy metals and nonionic surfactants. Strong colours may reduce light penetration, thus affecting the growth of plants and having impact on invertebrate and other forms of wildlife. There are a large numbe...
متن کاملKinetics of Chromium Sorption on Biomass Fungi from Aqueous Solution
The kinetics of chromium ions sorption from aqueous solution on fungi biomass have been investigated in a batch system. The experimental data were analysed based on an intraparticle diffusion equation and a pseudo-second-order mechanism, in order to predict the constant rate of sorption and the equilibrium capacity with the effect of initial chromium ions concentration, temperature and initial ...
متن کاملChemical modified bark for Cu (II) sorption from aqueous solution
In present study the removal of Copper ions from aqueous solution containing 100-800 mg/lit, using chemically modified Acacia bark was performed on laboratory scale. The chemical modification was done by treating grinded bark with formaldehyde in acidic medium. The Cu (II) is exchanged against protons on the modified bark that contain carboxyl groups in both pectin and tannin compounds. The eff...
