摘要
本文采用泡沫去污技术对后处理厂模拟污染样品进行了去污实验研究。实验结果表明 ,在室温条件下 ,采用泡沫去污技术 ,酸性去污剂对模拟样品有较好的去污效果。去污 90 min,硫酸高铈去污剂对不锈钢样品去污系数为 12 .4～ 2 4 .1,对涂漆碳钢样品为 3.6 2～ 5 .14;草酸去污剂对不锈钢样品的去污系数为 8.87～ 14.34,对涂漆碳钢样品为 6 .5 7～ 8.4 0。
Using chemical foam decontamination technique,decontaminati ng experiments on simulant contaminated samples of reprocessing plant were carri ed out. Results show that ceric sulfate foam has excellent decontamination effec t, DF(stainless steel)=12.39~24.08, DF(carbon steel)=3.62~5.14; for oxal ic acid foam, DF(stainless steel)=8.87~14.34, DF(carbon steel)=6.57~8.40 , at room temperature. It is believed that these acid foams can be applied in de contamination of nuclear facilities with large volume,complex form and fold rus t. The test gives a great evidence for engineering-scale test. (
