A few biosorbents have been reported for the adsorption of heavy metals not only in the form of metallic ions but also organometallic compounds. Saglam et al. [142] have prepared the biosorbents by the biomass of Phanerochaete chrysosporium which adsorbed inorganic mercury and alkylmercury species with an affinity of CH 3 HgCl ...

The present review also highlights the necessity for the examination of biosorbents within real situations, as competition between solutes and water quality may affect the biosorption performance. Thus, this article reviews the achievements and current status of biosorption technology, and hopes to provide insights into this research frontier. ...

Such equilibrium sorption isotherms can be used to compare different biosorbents, as well as to compare the affinities of different substances for the same biosorbents. In simple terms: V is the volume (L) of solution contacted with the sorbent; C i and C are initial and equilibrium (final) concentrations of the sorbate (mg L −1 ); S is the ...

The design of better biosorbents for improving their physico-chemical features as well as enhancing their biosorption characteristics has been discussed. Better economic value of the biosorption technology is related to the repeated reuse of the biosorbent with minimum loss of efficiency. In this context desorption of the metal pollutants as ...

Biosorbents using plant leaf biosorbents is a promising and eco-friendly method that can be used to remove phosphorus present in water (Yee, 1966, Huang and Chiswell, 2000). Biosorbents is an eco-friendly and cost-effective alternative to wastewater treatment procedures for eradicating heavy metals and other contaminants.

1. Introduction. The rapidly escalating industrial activities release toxic heavy metals (HMs), which pose a serious hazard to ecosystems and human health [1,2,3].Environmental HM pollution in soil and water reduces crop production and can be detrimental to health safety through food chains owing to industrial solid waste, and …

The results obtained for the determination of active sites and the point of zero charge (pH pzc) of biosorbents are presented in Table 1.It is noticed that on the surface of the biosorbents coexist acidic and basic groups, which can be modified by the type of treatment that is applied to the material, therefore the pH pzc of biosorbents is …

Biosorbents provide the binding sites for metal biosorption, and hence its dosage strongly affects the biosorption process . The increase of the biosorbent dose at a given initial metal concentration increases the biosorption of metal ions due to greater surface area which in turn increases the number of available binding sites . At lower ...
