Removal of Dyes by Biosorption on Biomass Ash

Review on Biosorption of Dyes by Fungi

Microorganisms dead or alive are successfully exploited for bioremediation of xenobiotics by biosorption. Textile effluents are among the most difficult-to-treat wastewaters, due to their considerable amount of recalcitrant and toxic substances. Fungal biosorption is viewed as a valuable additional treatment for removing pollutants from textile wastewaters. The overall economics of the biosorpt...

Radionuclide Biomass Biosorption by Bacterial

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...

Column studies for biosorption of dyes from aqueous solutions on immobilised Aspergillus niger fungal biomass

Biosorption is becoming a promising alternative to replace or supplement the present dye removal processes from dye wastewaters. Based on the results of batch studies on biosorption of the dyes on powdered fungal biomass, Aspergillus niger, an immobilised fungal biomass was used in column studies for removal of four dyes, Acid Blue 29, Basic Blue 9, Congo Red and Disperse Red 1 from aqueous sol...

Electrodialytic removal of Cd from biomass combustion fly ash suspensions.

Due to relatively high concentrations of Cd, biomass combustion fly ashes often fail to meet Danish legislative requirements for recycling as fertilizer. In this study, the potential of using electrodialytic remediation for removal of Cd from four different biomass combustion fly ashes was investigated with the aim of enabling reuse of the ashes. The ashes originated from combustion of straw (t...
