โฆ Synopsis
The uses of microorganisms, including live and dead bacterial biomass such as the actinomycetes, have been widely studied. In the present work flotation is proposed as the separation stage for harvesting suspended microorganisms following biosorption of cadmium. The parameters investigated in batch mode were solution pH, ionic strength, use of a frother (ethanol) and a cationic collector (cetyl trimethylammonium bromide) and biomass elution by EDTA. 1he process was also compared with cadmium ion flotation. Promising results were obtained with dead Streptomyces biomass in dilute aqueous cadmium solutions.

## Abstract Treatment of flax shive with sulfuric acid produces a carbonaceous material that has been used to remove metal ions from aqueous solution. Metal ions including Cd(II), Cu(II), Cr(III), Co(II), Ni(II), Zn(II) and Pb(II) have been investigated for kinetic behaviour and sorption capacities
The synthesis of poly( N,N-dimethylacrylamide-co-acrylic acid) under different feed molar ratios was carried out by radical polymerization. Both homopolymers were also synthesized to compare the metal ion binding abilities. All polymers were water-soluble and were characterized by FTIR, 1 H-NMR, 13
