“…Recently, the removal of metals, compounds and particulates from solution by biological material is recognized as an extension to adsorption and is named as biosorption [11]. Examples of biosorbents are [12], Algae [13], seaweeds [14] microorganisms [15], [16] and several biopolymers [17]. Chitin, which is the major component of carapaces, crusts and shells of crustaceans is the second most abundant organic resource next to cellulose on earth and the most abundant biopolymer in nature that is widely used for the adsorption of heavy metal ions [18], [19].…”

Abstract-The Biosorption of Copper (II) ions from aqueous solution on natural biosorbent (Mussels) has been investigated. Batch shaking adsorption experiments were performed and equilibrium and kinetic isotherms were tested. Results show that Chitin can remove Copper (II) effectively from aqueous solution. To predict the adsorption isotherms and to determine the characteristic parameters for process design, eight isotherm models:Langmuir, Freundlich, Elovich, Temkin, Fowler-Guggenheim, Jovanovic, Koble-Corrigan, and Hill were applied to experimental data. The equilibrium data were analyzed. The results reveal that the adsorption isotherm models fitted the data in the order: Jovanovic > Freundlich , Koble-Corrigan> Temkin> Fowler-Guggenheim> Elovich> Langmuir, Hill. Adsorption kinetic data were tested using pseudo-first order, pseudo-second order and Elovich model. The kinetics of the adsorption were found to fit the Elovich model.

Agro-waste materials have carboxylic and phenolic groups that play the main role in metal adsorption. The advantages of these materials include easy availability, low cost, and reasonable metal removal capacity. One of the materials (usually considered as waste) is pea waste (pods). Present work comprises adsorption of chromium from aqueous solution using powder of pods of garden peas (Pisum sativum) in batch. Important parameters like adsorbent dose, pH, contact time, and agitation speed were studied. Adsorption equilibrium was explained by Langmuir, Freundlich, and Temkin isotherms. Maximum chromium uptake (q m ) was 3.56 mg/g of adsorbent.Heat of adsorption, as evaluated by Temkin isotherm was 1.96 kJ/mol. It is proposed that pea pods can be an effective and environmentally benign (green) adsorbents for removal of chromium from industrial effluents and waste waters.

“…Cell walls of microbial biomass, mainly composed of polysaccharides, proteins and lipids have different functional groups for interactions with metal ions such as aldehydic, ketonic, amide, carboxyl, sulphate, phosphate and amino groups. This type of biosorptionusually rapid than metabolism dependent mechanisms and can be reversible [30,31] from the waste water [59][60][61][62][63][64][65][66].…”

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.
