A kinetic study of cadmium and lead biosorption to a brown alga, Kjellmaniella crassiforia, was carried out. The shrinking core model derived by M. Gopala Rao and A. K. Gupta (Chem. Eng. J.24, 181, (1982)) was modified and adapted for description of the rate process of cadmium and lead biosorption to the alga. The biosorption rate process was well described and average apparent diffusion coeffi...

Biosorption of heavy metals by bacterial biomass has been the subject significant research interest in last decades due to its efficiency, relatively low cost and minimal negative effects for surrounding environment. In this meta-analysis, biosorption efficiencies different strains Cu(II), Cd(II), Zn(II), Cr(III), Mn(II), Pb(II) Ni(II) were evaluated. Optimum conditions process such as initial ...

This study focuses on identifying relationships between the content of heavy metals in water and resistance patterns different bacteria. Samples from watercourses one most important mining areas Mexico were collected. Seventy-one bacteria isolated, their to Cr, Zn, Cu, Ag, Hg, Co was studied. The Minimum Inhibitory Concentration range determined, a Multiple Metal Resistant index calculated. Aft...

The present study aims to evaluate the competitive biosorption of lead, cadmium, copper, and arsenic ions by using native algae. A series of experiments were carried out in a batch reactor to obtain equilibrium data for adsorption of single, binary, ternary, and quaternary metal solutions. The biosorption of these metals is based on ion exchange mechanism accompanied by the release of light met...

The paper discusses various aspects of biosorption of microelements by marine seaweeds to be used as mineral feed supplement for livestock. n the study, biosorptive properties of a single marine species Cladophora rupestris and mixed species of algae from the Baltic Sea (a mixture f Cladophora sp. and Enteromorpha prolifera) were investigated. The mechanism of biosorption was identified as cati...

The study involves the batch biosorption process for the removal of Chromium in the aqueous solution using the dried pods of Prosopis spicigera. Factors influencing the biosorption are pH, contact time, adsorbent dose and initial metal ion concentration. Characterization of the biosorbent is carried out to study the morphology by using Scanning Electron Micrograph (SEM). The maximum biosorption...

Over the past 25 years, intensifying research into metal biosorption elucidated the principles of this effective metal-concentration phenomenon. Biosorption can be cost-effective particularly in environmental applications where low costs of the metal removal process are most desirable. Some efficient natural biosorbents have been identified that require little modification in their preparation....

Metal accumulation in the environment as a result of mining and metallurgical activities is arising as a matter of serious concern. The removal and recovery of metals from hydrometallurgical solutions and waste water prior to their release to the environment are important in preserving the ecosystem as well as from an economical perspective. There are several technologies used to recover metals...
