Sequential extraction of Cs and Sr from Ain Oussera soils around Es-Salam research reactor facility

摘要: Four types of undisturbed soil in Ain Oussera region around the Es-Salam reactor facility, located south Algiers, Algeria, at about 200km, were artificially contaminated for one year with stable CsCl and SrCl2 order to simulate an accidental release these elements. This study was performed using sequential extraction procedure based on Shultz method containing six fractions. The selectivity protocol confirmed by analyzing some elements (Ca, C, Fe, Mn, Si Al) designed as indicators targeted phases. obtained results showed acceptable reproducibility, view coefficients variation that most cases less than 15%. revealed a clear proportional correlation between extracted Cs Sr fractions each soils physicochemical properties. Organic matter appears play important role retention, particularly where percentage exceeds 30% whole soils. In contrast, strontium expresses remarkable affinity fraction bound carbonates. data also indicate availability four is compared availability. illustrated higher value easily extractible phase, including water-soluble exchangeable fraction.
