nickel biosorption from aqueous solutions using bios lids

Ions from Aqueous Solutions by Biosorption Processes

Due to the disadvantages of heavy metal removal from aqueous sytems by conventional methods, alternative new methods have been investigated lately. Biosorption is one of these new methods. In this method, metal ions are transported into cell structure, and removal is ensured by several mechanisms that occured between living or non-living microorganisms and metal ions. The metal removal, the use...

Biosorption of Pentachlorophenol from Aqueous Solutions by Aspergillus Niger Biomass

Background: This study aimed to investigate the biosorption of pentachlorophenol on Aspergillus niger biomass as a method for removal of pentachlorophenol from aqueous solutions. Methods: Modified A. niger biomass with NaOH was used to absorb the pentachlorophenol. The impacts of various experimental parameters like primary pentachlorophenol concentration, pH of the solution, contact time, a...

biosorption of cr (iii) from aqueous solutions using indigenous biomaterials

in the present study, an indigenous medicinal plant, tridax procumbens (asteraceae) was used as bioadsorbent for the removal of cr (iii) ions from synthetic wastewater and the method was also applied for real sample analysis. the biosorption of cr (iii) was a two-stage batch reactor process. in the first stage, raw biomaterial was used to the conversion of cr (vi) into cr (iii). the amount of t...

Biosorption of Cu2+ from aqueous solutions by pretreated Cladosporium sp.

In this paper, adsorption properties of a pretreated of Cladosporium sp. for Cu2 were studied. The fungi pretreated with some chemical reagents exhibited higher Cu2+ removal capacities than native biomass. The optimum chemical reagent was 0.2M NaOH. After 0.2M NaOH pretreatment, optimum conditions of biosorption were found to be pH 5.0, temperature 35 degrees C, and stirring speed of 100rpm. Eq...

Cr(VI) ADSORPTION – MECHANISTIC APPROACH FOR BIOSORPTION FROM AQUEOUS SOLUTIONS

Biosorption of Mercury (II) from Aqueous Solutions onto Fungal Biomass

The biosorption of mercury (II) on 14 fungal biomasses, Aspergillus flavus I-V, Aspergillus fumigatus I-II, Helminthosporium sp., Cladosporium sp., Mucor rouxii mutant, M. rouxii IM-80, Mucor sp 1 and 2, and Candida albicans, was studied in this work. It was found that the biomasses of the fungus M. rouxii IM-80, M. rouxii mutant, Mucor sp1, and Mucor sp 2 were very efficient removing the metal...
