本文叙述了磷酸锡-AMP(磷钼酸铵)的制备及其对~(137)Cs的交换性能,测定了不同制备条件所得产物对交换容量的影响,做了吸附-淋洗实验和~(60)Co γ辐照实验,求出了C/Co=0.01时的击穿容量和~(137)Cs的回收百分数。用相应的放射性料液配制模拟液进行了~(137)Cs的回收实验,对回收的~(137)Cs产品用γ能谱法测定了γ杂质含量;用~(85-89)Sr作指示剂,通过实验和计算求出了在~(137)Cs产品中Sr的百分含量。
In this paper, the preparation of tin phosphate-AMP (ammonium phosphomolybdate) and its exchange performance for ~ (137) Cs were described. The effects of the products obtained under different preparation conditions on the exchange capacity were investigated. The adsorption- 60) Co γ irradiation experiments, the breakdown capacity and recovery percentage of 137 Cs were obtained at C / Co = 0.01. The recovery experiment of 137 Cs was carried out by using the corresponding radioactive liquid to prepare the simulated liquid, and the γ impurity content of the recovered 137 Cs was measured by gamma spectrometry. The content of γ was determined by ~ (85-89) Sr The percentages of Sr in ~ (137) Cs were calculated experimentally and calculated.
