放射性废物泥浆中90Sr,137Cs和239,240Pu的化学形态分析
ANALYSIS OF CHEMICAL SPECIATION OF 90Sr, 137Cs AND 239,240 Pu IN THE RADIOACTIVE SLUDGE WASTE
【摘要】 采用连续提取法和平行提取法分析了放射性废物泥浆中90 Sr,137Cs和2 39,2 4 0 Pu的化学形态。实验结果表明 ,90 Sr主要以碳酸盐键合态和有机物键合态存在 ,137Cs主要以残渣态存在 ,2 39,2 4 0 Pu主要以有机物键合态和残渣态存在
【Abstract】 The sequential extraction and parallel extraction methods have been used to estimate the chemical speciation of 90 Sr, 137 Cs and 239,240 Pu contained in the radioactive sludge waste. It is found that 90 Sr mainly exists in bonded state with organic substances, 137 Cs is predominate present as insoluble residual and 239,240 Pu exists both in bonded state with organic substances and as insoluble residual.
