| 摘 要： | 为考察优先污染物丙烯腈在γ辐照下的去除情况,选取了高浓度的丙烯腈废水作为研究对象,利用60Co作为γ射线源进行辐照分解,并利用吡啶比色法测定水中丙烯腈的含量,研究了丙烯腈的辐照降解。结果表明:辐照剂量为15kGy时,丙烯腈去除率随初始浓度的增大而增大;初始质量浓度为4g/L的丙烯腈溶液,随着辐照剂量的增大,丙烯腈的去除率先增加后减小,10 kGy时的去除效果最佳,去除率达到90%以上;在中性条件下的去除效果要好于偏酸或偏碱性条件;添加FeCl3对丙烯腈去除率的影响很小。

| Abstract: | The degradation of acrylonitrile(AN) in aqueous solution by gamma radiation was investigated to study the feasibility of radiation treatment of acrylonitrile wastewater.60Co was used as the radiation source.The acrylonitrile concentration was analyzed using the pyridine colorimetric method.The experimental results show that the AN removal efficiency increased with increasing of the initial concentration at radiation dose of 15 kGy.When the initial AN concentration was 4 g/L,the removal efficiency first incr... |
