采用连续提取法和平行提取法分析了放射性废物泥浆中90Sr,137Cs和239,240Pu的化学形态。实验结果表明,90Sr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,239,240Pu主要以有机物键合态和残渣态存在。
採用連續提取法和平行提取法分析瞭放射性廢物泥漿中90Sr,137Cs和239,240Pu的化學形態。實驗結果錶明,90Sr主要以碳痠鹽鍵閤態和有機物鍵閤態存在,137Cs主要以殘渣態存在,239,240Pu主要以有機物鍵閤態和殘渣態存在。

The sequential extraction and parallel extraction methods havebeen used to estimate the chemical speciation of 90Sr,137Cs and239,240Pu contained in the radioactive sludge waste. It is found that 90Sr mainly exists in bonded-state with organic substances, 137Cs is predominate present as insoluble residual and 239,240Pu exists both in bonded-state with organic substances and as insoluble residual.
