Radionuclide Biomass Biosorption by Bacterial

Statistical Analysis and Optimization of Acid Dye Biosorption by Brewery Waste Biomass Using Response Surface Methodology

Biosorption of Acid Yellow (AY 17) and Acid Blue (AB 25) were investigated using a biomass obtained from brewery industrial waste spent brewery grains (SBG). A 2 full factorial response surface central composite design with seven replicates at the centre point and thus a total of 31 experiments were employed for experimental design and analysis of the results. The combined effect of time, pH, a...

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 Cd2+ and Cu2+ from aqueous solution using Gracilaria corticata waste biomass

Pollution of aquatic environments by toxic trace metals has been taking place because of discharge of untreated effluents from many industrial processes. Conventional methods used for removing dissolved heavy metal ions from wastewaters have significant disadvantages including incomplete metal removal, requirements for expensive equipment, high energy requirements and generation of toxic sludge...

Biosorption of Pb(II) and Co(II) on Red Rose Waste Biomass

In the present investigation the biosorption potential of rosa gruss an teplitz (Red Rose) Waste Biomass (RRWB) for the removal of Pb(II) and Co(II) from aqueous solutions was studied. The effect of different process parameters such as pH, biosorbent dose, biosorbent size, temperature, contact time, initial metal concentration and pretreatments on the biosorption capacity of this waste biom...
