Краткое описание
Abstract—The sorption characteristics of the Kara sea bottom sediments were investigated. The sediments were collected during scientific expedition of the R/V Akademik Mstislav Keldysh (Cruise AMK-66). The mineral and fraction composition of the sediments was determined. It has been found that 137Cs is sorbed mainly by an ion exchange mechanism because of the clay minerals presence in sediments. At the same time, 243Am and 90Sr sorbed from seawater by the surface complexation mechanism. It has been established that the sorption kinetics of 243Am, 137Cs, and 90Sr is about 20 hours, 2 hours, and less than an hour, respectively. The Cs and Am sorption isotherms in experiments with sea and deionized water are described by the Henry equation. The Sr behavior in the deionized and sea water is described by the Langmuir and Freindlikh equations, respectively.
