Natural biosorbents for the removal of metals from aqueous solutions
… Conventional treatments, chemical precipitation, adsorption by activated carbon, ion-exchange, electro-chemical and reverse osmosis can be expensive or ineffective at low concentrations. Recent research has shown that biosorption by low cost biomass can be an effective alternative. Biosorption is …

Fabrication of Biomass-Polymeric Adsorbent for the Removal of Selected Metal Species, Nutrients and Pathogens in Aqueous Solutions
… and initial concentration. The respective adsorption kinetics processes by the GFP, diatom biomass, GFP/diatom, and pPD/GFP/diatom sorbent materials on Cr6+, Cd2+, and PO43- ions revealed that physisorption and chemisorption mechanisms were responsible for the adsorption processes as well …

Sorption of Cadmium, Copper, Lead, and Zinc as influenced by pH, ionic strength and selected soil components
… of copper-rich pig manure for 16 years. Adsorption of Cd, Cu, Pb, and Zn as affected by different background electrolytes at various concentrations was investigated. Electrolytes were Na+, Ca2+, or Al3+ in perchlorate solution, and their concentrations ranged from 0.001 to 0.5 molc L-1. …

Bacterial poly-gamma-Glutamic Acid (y-PGA) - a promising biosorbent of heavy metals
… of interfering metal ions could hinder the adsorption of individual metal ions by γ-PGA. The affinities of heavy metal ions for γ-PGA followed the order: Cu2+ > Zn2+ > Ni2+ > Cd2+. The effect of molecular weight of γ-PGA on metal removal was also investigated, and it was found that metal ion …
