Abstract
The radiocesium interception potential (RIP) characterizing the ability of a sorbent to retain 137Cs+ cations in the presence of competing K+ or NH4+ cations [RIP(K) or RIP(N)] under the conditions controlled by selective sorption was determined for various materials. RIP(K) (mg-equiv kg–1) is 44–720 and 260–1200, and RIP(N), 21–189 and 96–250 for sapropels of the organic and silica types, respectively. For sapropels of the organic type, the selectivity coefficient Ks(N/K) for the 137Cs-selective sorption sites varies from 2.1 to 3.8, and for silica sapropels (Lake Dobeevskoe) it reaches 4.5–4.8, suggesting the presence of illite-type particles, which significantly influence the 137Cs uptake by these types of sapropels. The highest RIP(K) values for the sapropels studied are reached at the organic to mineral matter ratios in the interval 0.43–0.61.
