The kinetics of radium biosorption
The Chemical Engineering Journal, 1986Abstract The intrinsic rate of radium adsorptive uptake by two types of waste inactive microbial biomass was examined. The effects of solution initial radium concentration, pH and ionic composition on the observed rate were also investigated. The results show that radicum uptake rates are reasonably rapid, with equilibrium attained after less than 2 ...

Biosorption is the method to remove heavy metals from the ecosystem, and it has replaced the use of other physical and chemical methods that are used for removal of heavy metals. The main cause of heavy metal pollution is industrialization. The industrial waste that contains heavy metal leads to pollution in aquatic life systems.

Modeling of Biosorption Processes
2010Biosorption entails the use of microbial or plant biomass, usually inactivated, to remove toxic metal ions in aqueous solutions. It is particularly effective in dealing with low concentration, high volume metal waste streams. Although biosorption processes have not yet been commercialized to any significant extent, they offer a promising area for ...

Potential of Biosorption Technology
2011Heavy metal removal from inorganic effluent can be achieved by conventional treatment such as chemical precipitation, ion exchane or flotation, however each treatment has its limitation. Recently, sorption, namely biosorption has become one of the alternative treatments. Basically, sorption is a mass transfer process by which a substance is transferred

BIOSORPTION OF HEAVY METALS BY FUNGAL BIOMASS AND MODELING OF FUNGAL BIOSORPTION: A REVIEW
Separation and Purification Methods, 2001The wastewaters discharged from chemical industries which may contain heavy metal ions have toxic effect on all the living organisms. Because of this, disposal of them to the environment is a major threat to both human health and ecosystem. So the development of new technologies is required to treat wastewaters as an alternative to traditional ...

The term biosorption describes the passive (i.e. not metabolically mediated) binding of heavy metals by dead or living biomass. The term bioaccumulation, on the other hand, refers to active processes which require the metabolic activity of living organisms. Biosorption can be employed to eliminate heavy metals from industrial effluents (e.g.

Fungal Biosorption and Biosorbents
2011The common filamentous fungi can sorb heavy metals from aqueous solutions. Fungal biosorption largely depends on parameters such as pH, metal ion and biomass concentration, physical or chemical pretreatment of biomass, presence of various ligands in solution, and to a limited extent on temperature.

Biosorption of Pharmaceutical Pollutant
2015The adsorption of penicillin onto dried biomass was studied as a function of initial penicillin concentration and temperature. The maximum penicillin adsorption yield was obtained at the temperature of 30 °C; the equilibrium uptake increased with increasing initial penicillin concentration.
