“…Some other studies reported that most of the biosorbion was achieved in 5 to 15 min. The fluctuation of equilibrium period was recorded by many workers and depended in many factors of which the type and nature of the biomass, pH, metal ions, and physicochemical properties of the biosorption process (Saglam et al, 1999;Kacar et al, 2000;Abu Al-Rub et al, 2004;Herrero et al, 2005;Bayramoglu et al, 2006;EL-Sherif et al, 2008;Parameswari et al, 2009;Al Garni et al, 2009).…”

“…The main assumption of pseudo second order kinetic model is that the rate limiting steps may be chemical sorption involving forces through exchange or sharing of electrons between the metal ions and the biomass [22]. The Elovich kinetic constants (α and β) could be deduced from the slope and intercept of the linear plots of Qt against ln(t).…”

Batch adsorption techniques were used to study the biosorption of Lead and Nickel from aqueous solutions by Flame of the forest pods. The effects of optimum pH, contact time, metal ion concentration, biosorbent dose, biosorbent particle size and the presence of sodium, calcium and magnesium interfering ions on the sorption were investigated. Experimental results showed that Delonix regia biomass was effective in removing these metals from aqueous solutions as the equilibrium biosorption of both metals was attained within 60 minutes of interaction with 98% of the metals removed within this period. Sorption of these metals was dependent on pH as maximum removal was attained at pH 4 and pH 5 for Lead and Nickel ions respectively. Adsorption experiments showed that the process followed the pseudo second order kinetic model with high r 2 (0.9999) and the equilibrium data fitted well with Langmuir and Freundlich isotherm models. The presence of competing ions impacted negatively on the sorption process irrespective of the type used. 27% and 36% of lead (II) were recovered from the spent biosorbents with 1 M HCl and disodium salt of EDTA solutions respectively.

“…This situation is a result of industrial activities which are related to the population growth, urbanization and industrialization [1,2]. The toxic effect of heavy metals on the environment and living organisms is observed even at low concentrations, due to their accumulation in the food chain [3,4].…”

“…This is due to the rapid uptake of metal ions, low cost and high efficiency of the process, energy and time saving, fast growth rate of the biomass and the possibility of reuse. The heavy metal ions uptake by algal biomass is connected to the ion exchange process [1,4,9,16,17]. The used algal biomass could be used as a feedstock for e.g.…”

Non-modified and chemically modified algal biomass of Chlorella vulgaris and Scenedesmus armatus were chosen to examine their Zn 2+ , Pb 2+ and Cd 2+ sorption activity. The dry biomass was chemically modified with 1M HNO3 in order to determine the influence of acid--treatment on the heavy metal ions removal rate. The heavy metal uptake process was found to be rapid and very efficient. The sorption process of heavy metals is highly pH-dependent. It influences heavy metal forms in the solution, and functional groups located on the cell surface. The effectiveness of biosorption depends also on the biomass concentration and its modifications. The highest adsorption capacities of both, Chlorella vulgaris and Scenedesmus armatus towards zinc, lead and cadmium ions were found for the lowest sorbent concentrations. Batch experiments showed that the differences between uptake by non-modified and acid-modified biomass are relatively small. It can be due to the fact that non-modified algal biomass exhibits high sorption capacity.
