-The performance of Salvinia natans macrophyte to recover lead and chromium from single and bicomponent solutions in batch and fixed bed systems was investigated. Equilibrium data were obtained through isotherms and fitted to Langmuir, Freundlich and D-R models for a single component system. In the fixed bed study the breakthrough curves were carried out at three different ratios of concentrations for the bicomponent study and at the concentration of 1 mmol.L -1 for the single system. In order to know the biosorption mechanism, FT-IR analyses were performed for S. natans before and after the uptake of metal ions. The results showed different functional groups in the biomass and the ability of these groups to bind Cr are not common in the literature, which makes the experimental data obtained in this work very important for providing information that could be used in adsorption processes.

“…A list of conventional technique can be identified for the removal/ concentration of Cadmium from the aqueous media. It includes reverse osmosis, evaporation, sedimentation, adsorption, coagulation, ion exchange etc [5][6][7][8][9][10] . Each of aforementioned technologies is hindered by the economical problem when applied for the remediation of dilute metal solutions.…”

The contemporary investigation presents a fundamental study on the removal of Cd(II) by ripped Citrus Paradisi pulp waste (RCPW). The effects of various engineering parameters such as initial solution pH, biosorbent dose, agitation, contact time, initial concentration, temperature and different eluents were evaluated on the uptake of Cd(II) by RCPW. Optimum uptake of Cd(II) onto RCPW was observed at 6.5 pH, 0.05 g of biosorbent and 100 rpm. Pseudo second order kinetic model best described the process of Cd(II) uptake by RCPW. Results showed that the sequestration of cadmium on RCPW was in monolayer as described by Langmuir's Model. Increase in temperature negatively affected the biosorption capacity of Cd(II) on RCPW indicating exothermic nature of the phenomenon. 0.1N NaOH was found to be the best desorbent among HNO 3 , H 2 SO 4 , HCl and EDTA.

“…The anthropogenic activities for heavy metal exposure are refineries, coal burning in power plants, high tension lines, textiles, plastic, microelectronics, and wood preservation and paper processing plants [11][12][13][14][15][16][17][18]. Conventional method used for the removal of metals and heavy metals from water or waste water are chemical precipitation, carbon adsorption, ion exchange, evaporations and membrane processes, ultra filtration, electro winning, pre concentration and reverse osmosis [19][20][21][22]. The biosorption process used for the removal processes is an efficient, low cost, takes no longer time, harmless to environment and economical [20][21][22][23][24][25].…”

ABSTRACT:Biosorption is an efficient technique for the removal of heavy metal contaminants from water or waste water. The water pollution due to heavy metals is one of the challenging issues in the world. The conventional methods are applying for the removal processes of heavy metal are expensive or takes long time or has less efficiency or not economical. As the availability of cheap bio sorbents, it becomes more reliable and economical process. Most of the biosorbents are waste materials of the part of animal and plants and their efficiency can increase by their chemical modifications. Biosorption process not only used to remove heavy metals but can also be used in the metal recovery. Metals cannot invent in laboratories or industries but they persist in the water bodies.Most of heavy metals are essential for the growth and development of organism below the considerable limits but beyond the limit they are definitely hazardous to all living organisms.Biosorption process is a part of sustainability and can remove the metallic pollutant at their sources and minimize the fresh water pollution. Cost is also an effective parameter for applying a process in the large scale and biosorption is very cheap and requires minimization of chemicals or instruments/apparatus.
