Biosorption of trivalent chromium on the brown seaweed biomass.
Biosorption has attracted attention as a cost-effective means for the treatment of metal-bearing wastewater. However, the mechanism of metal binding is not clearly understood, and consequently, modeling of the biosorption performance is still raising debates. In this study, the biosorption of trivalent chromium was investigated with protonated brown alga Ecklonia biomass as a model system. Titr...
متن کاملBiosorption of Cr (VI) with Trichoderma viride immobilized fungal biomass and cell free Ca-alginate beads.
Ability of Cr (VI) biosorption with immobilized Trichoderma viride biomass and cell free Ca-alginate beads was studied in the present study. Biosorption efficiency in the powdered fungal biomass entrapped in polymeric matric of calcium alginate compared with cell free calcium alginate beads. Effect of pH, initial metal ion concentration, time and biomass dose on the Cr (VI) removal by immobiliz...
متن کاملBiosorption and elution of chromium from immobilized Bacillus coagulans biomass.
Bacillus coagulans, a tannery wastewater isolate, previously shown to bind dissolved Cr(VI), retained its ability to biosorb Cr(VI) in different matrices. Polymeric materials like agar, agarose, calcium alginate and polyacrylamide were screened. Agarose emerged as the suitable candidate for biomass immobilization mainly due to its higher stability and integrity in acidic pH. Aptness of agarose ...
متن کاملCHROMIUM (VI) BIOSORPTION BY IMMOBILIZED BIOMASS OF Bacillus cereus
Toxic heavy metal contamination of industrial wastewater is an important environmental problem. Many industries such as electroplating, pigments, metallurgical processes, and mining and leather industries release various concentrations of heavy metals like chromium. Chromium generally exists in different forms, mostly as trivalent and hexavalent forms. Trivalent chromium is nontoxic and relativ...
متن کاملBiosorption of Chromium from Tannery Effluent Using Biomass of Sargassum
The release of chromium into water bodies is one of the major concerns of tannery industries. The present work deals with the determination of Chromium removal capacity of powdered biomass of Sargassum wightii (Greville) in synthetically prepared as well as real tannery effluent. The maximum adsorption was obtained after 12 hours of exposure at pH-4, in 8g/L biomass concentration of the seaweed...
