Comparative Study on Heavy Metals Biosorption by Different Types of Bacteria

Biosorption of Cd(II), Ag(I) and Au(III) by cyanobacteria Spirulina platensis, of Au(II)—by Streptomyces spp. 19H, and of Cr(VI) and Cr(III)—by Arthrobacter species was studied by using the dialysis and atomic absorption analysis under various conditions. In particular, the impact of the following parameters on biosorption was studied: pH (for Ag, Cd, Au), living and non-living cells (for Cr), ...

Comparative study of biosorption of heavy metals using different types of algae.

Sorption capacity of six different algae (green, red and brown) was evaluated in the recovery of cadmium, nickel, zinc, copper and lead from aqueous solutions. The optimum sorption conditions were studied for each monometallic system. The optimum pH was 6 for the recovery of Cd, Ni and Zn, and less than 5 for Cu and Pb. The best results were obtained with the lowest biomass concentration used (...

Heavy metals biosorption by mushrooms

The use of absorbents of biological origin has emerged in the last decade as one of the most promising alternatives for the control of environmental pollution caused by heavy metals. A number of methods, viz. chemical precipitation, evaporation, electroplating, ion exchange, membrane, processes, etc. exist for the removal of heavy metals from liquid wastes. All these methods are expensive and h...

Biosorption of Heavy Metals

The discharge of heavy metals into aquatic ecosystems has become a matter of concern in India over the last few decades. These pollutants are introduced into the aquatic systems significantly as a result of various industrial operations. Industrialization in India gained a momentum with initiation of five year developmental plan in the early 50's. The pollutants of concern include lead, chromiu...

Biosorption of heavy metals.

Only within the past decade has the potential of metal biosorption by biomass materials been well established. For economic reasons, of particular interest are abundant biomass types generated as a waste byproduct of large-scale industrial fermentations or certain metal-binding algae found in large quantities in the sea. These biomass types serve as a basis for newly developed metal biosorption...
