“…This buffer was u.sed beeanse boric acid is weakly dissociated and is i)robal)ly only absorbed as a neutral molecule, tbe nptake being dominated by permeability i)iu'nomena (13). Because the calciimi content of the medimn is of special imi)oitiuice (3,8,9,12,14,15,20), absorption media always contained 0.5 m.l/ of calcium sntphate except in the experiments where calcium was used as a competitor for zinc.…”

“…The potential practical importance of such biological materials for controlling the discharge of radioactive effluents was already recognized in the 1950s and 1960s (Pickering & Lucas, 1962). Compared to conventional treatment methods, biomass based systems are likely to be more acceptable in terms of both cost effectiveness and efficiency (Sar et al, 2004).…”

Adsorption of Radionuclides (134Cs, 85Sr, 226Ra, 241Am) by Extracted Biomasses of Cyanobacteria (Nostoc Carneum, N. Insulare, Oscillatoria Geminata and Spirulina Laxis-Sima) and Phaeophyceae (Laminaria Digitata and L. Japonica; Waste Products from Alginate Production) at Different pH

The extracted biomasses of four cyanobacteria (Nostoc carneum, Nostoc insulare, Oscillatoria geminata, and Spirulina laxissima) grown in axenic mass cultures, and of four samples of Laminaria obtained from different locations (L. digitata I and II, France; L. japonica I and II, China; all waste products from alginate production) were tested for their ability to adsorb four radionuclides ( 134 Cs, 85 Sr, 226 Ra, and 241 Am) under different pH regimes. In addition, two of the cyanobacterial biomasses (N. carneum and O. geminata) and the four Laminaria biomasses were phosphorylated before being tested as radionuclide adsorbers. The non-phosphorylated cyanobacterial biomasses showed very low adsorption of 134 Cs but substantially higher removal of 85 Sr and 226 Ra, which increased with increasing pH. 241 Am was almost completely removed from the solution at low pH, but less at higher pH. After phosphorylation, removal of 134 Cs, 85 Sr and 226 Ra by the cyanobacterial biomasses was improved, particularly at lower pH, but there was almost no adsorption of 241 Am. The non-phosphorylated P. Pohl ( ) Laminaria biomasses showed good removal of 134 Cs and very good adsorption of 85 Sr and 226 Ra. Removal of 241 Am was high at low pH but decreased with increasing pH. After phosphorylation, adsorption of 134 Cs by Laminaria samples was slightly improved; removal of 85 Sr and 226 Ra was increased at low pH with a tendency towards decrease in adsorption with increasing pH; but almost no 241 Am was adsorbed. The origin of the cyanobacterial and Laminaria materials appeared to have little effect on the adsorption of the radionuclides.
