“…The most prominent form of zinc available in industrial effluent is zinc ions (Mishra and Patel 2009). According to the list of organic and inorganic pollutants prepared by United States Environmental Protection Agency (USEP-A), zinc has been kept in the list of toxic metals with other 13 metals (Kumar et al 2006;Cesur and Balkaya 2007). The guidelines for the discharge of zinc in ground water, fresh water and estuaries mentioned by government agencies of various countries have been shown in Table 1.…”

Massive industrialization and urbanization of civilization during the last few decades have made a thrust in heavy metal pollution in various water bodies. In past, various kinds of conventional metal ion remediation technologies, such as cementation, osmosis, reverse osmosis, ultrafiltration, etc., have been practised. However, most of these technologies are quite expensive, and lead to the generation of secondary chemical sludge. However, biosorption of heavy metal ions is significantly inexpensive and an eco-friendly technology. Among the series of heavy metals, zinc has gained the significant interest due to its toxicity and easy availability in water bodies. Biosorption of zinc in liquid phase by living, nonliving, conventional and non-conventional biosorbents has been practised extensively in the past. This literature review focuses on the recent trends practised in the field of biosorption of zinc from liquid phase. The present work provides deep insight into various aspects of biosorption of zinc by different mechanisms of biosorption, bioaccumulation, isotherm, kinetic and mechanistic modeling. An exhaustive comparison among different sorts of biomasses has also been given in the present work to enlist all the milestones of biosorption.

“…Although biosorption has gained much attention, the exact interactions between the metal ions and the functional groups on the cell, the kinetics and the thermal properties of biosorption have not been well defined [10]. Literature reports reveal however, a large number of studies in which microorganisms have been used as biosorbents for heavy metals, and these studies may be useful for low cost industrial wastewater treatment where rapid removal of several heavy metals is needed [11][12][13][14]. Most studies have focused on the removal of Pb 2+ , Cd 2+ , and Ni 2+ from wastewater by using various biosorbents.…”

The biosorption of lead(II), cadmium(II) and nickel(II) ions from aqueous solution by Spirulina platensis was studied as a function of time, concentration, temperature, repetitive reactivity, and ionic competition. The kinetic results obeyed well the pseudo second-order model. Freundlich, Dubinin Radushkevich and Temkin isotherm models were applied in describing the equilibrium partition of the ions. Freundlich isotherm was applied to describe the design of a single-stage batch sorption system. According to the thermodynamic parameters such as G• , H • and S• calculated, the sorption process was endothermic and largely driven towards the products. Sorption activities in a three metal ion system were studied which indicated that there is a relative selectivity of the biosorbent towards Pb 2+ ions. The measurements of the repetitive reusability of S. platensis indicated a large capacity towards the three metal ions.

“…In recent years, the searches for low-cost agricultural by-products have been widely studied for metal ion removal from water and wastewater. These include Citrus reticulata [4], maize cob [5], Tectona grandis leaves [6], neem biomass [7], Eucalyptus camaldulensis leaves [8], rice straw [9], rice husk [10], Eucalyptus bark, mango bark and pine apple fruit peel [11], Moringa oleifera bark [12], hazelnut, almond and walnut shells [13], Pinus gerardiana leaves [14], Cynodon dactylon, Psidium guajava, Azadirachta indica, Cassia tora and Cassia angustifolia leaves [15], coconut leaves [16], Ashoka leaf [17], Ceratonia siliqua bark [18] and Eriobotrya japonica bark [19]. This paper presents the study of biosorption characteristics of Sophora japonica pods powder (Sjp) for the removal of Cu(II), Ni(II), Zn(II) and Pb(II) ions from aqueous solution in batch process.…”

Background Biosorption of Cu (II), Ni(II), Zn(II) and Pb(II) ions from aqueous solutions onto Sophora japonica pods powder has been studied using batch adsorption technique. The biosorption studies were determined as a function of pH, contact time, initial metal ion concentration, biosorbent dosage and temperature. Results The kinetic study showed that the biosorption of the Cu(II), Ni(II), Zn(II) and Pb(II) ions followed pseudosecond-order kinetic model. Experimental data obtained were analyzed with Langmuir, Freundlich, Dubinin-Radushkevich and Temkin isotherm models and in each case the Langmuir model appears to have better regression coefficients. Thermodynamic parameters: DG°, DH°and DS°were calculated indicating that the biosorption of Cu(II), Ni(II), Zn(II) and Pb(II) ions is spontaneous and endothermic process. Conclusions The results of the study showed that Sophora japonica pods powder can be efficiently used as a low-cost alternative for the removal of Cu(II), Ni(II), Zn(II) and Pb(II) ions from aqueous solutions.
