Application of biosorption for the removal of organic pollutants: a review

Zümriye Aksu
- 01 Mar 2005 - 
TL;DR: In this article, a review examines a wide variety of microorganisms (fungi, yeasts, bacteria, etc.), which are capable of uptake of organic pollutants, discusses various mechanisms involved in biosorption, discusses the effects of various parameters such as pH, temperature, concentrations of organic pollutant, other ions, and biomass in solution, pretreatment method, etc.

Heavy metal biosorption sites in aspergillus niger

Anoop Kapoor, +1 more
- 01 Sep 1997 - 
TL;DR: The role played by various functional groups in the cell wall of Aspergillus niger in biosorption of lead, cadmium and copper was investigated in this paper, where the biomass was subjected to chemical treatments to modify the functional groups, carboxyl, amino and phosphate.

Reactive dye biosorption by Rhizopus arrhizus biomass

T O’Mahony, +2 more
- 02 Sep 2002 - 
TL;DR: The biosorption of three commonly used reactive dyes, from aqueous solutions by oven-dried Rhizopus arrhizus biomass was studied in a batch system with respect to pH, initial dye concentration and initial metal ion concentration.

Binding of hard and soft metal ions to Rhizopus arrhizus biomass

Joseph M. Brady, +1 more
- 01 Sep 1995 - 
TL;DR: In this paper, the potential of the test ions to displace preloaded borderline metals ions from the biomass increased with increasing covalent index, except for Pb 2+, which totally displaced the preloaded Sr 2+.

The Attractions of Proteins for Small Molecules and Ions

George Scatchard
- 01 May 1949 - 
TL;DR: The number and variety of known compounrjs between proteins and small molecules are increasing rapidly and make a fascinating story as discussed by the authors, and there are many compounds of serum albumin, which was used during the war by many chemists, most of whom found at least one 6ew compound.

The adsorption of gases on plane surfaces of glass, mica and platinum.

Irving Langmuir
- 01 Sep 1918 - 
TL;DR: In this article, the absorption index at the wave length of the band maximum was found to be proportional to the total concentration of metal at shorter wave lengths, however, deviations were observed, the absorption increasing more rapidly with concentration than Beers' law would demand.

Hard and soft acids and bases

Ralph G. Pearson
- 01 Nov 1963 - 
TL;DR: In this paper, the rate data for the generalized nucleophilic displacement reaction were reviewed, and the authors presented a method to estimate the rate of the generalized displacement reaction in terms of the number of nucleophiles.

The replacement of the nondescript term ‘heavy metals’ by a biologically and chemically significant classification of metal ions

Evert Nieboer, +1 more
- 01 Jan 1980 - 
TL;DR: In this article, the authors proposed a classification of metal ions according to their binding preferences (i.e. whether they seek out O-, N- or S-containing ligands).
