摘要
通过模拟实验,采用紫外光和日光分别对污染土壤中氰化物进行了处理。结果表明:两种处理方法下,污染土壤中总氰化物(Total cyanide)、易释放氰化物(WAD cyanide)含量均随着处理时间的增加而减少;紫外光光照24 h或日光光照5 d后,总氰化物的含量分别减少了24.76%、33.87%,易释放氰化物的含量分别减少了18.89%、13.52%。
photolysis of cyanide from polluted soil with UV rays or sunlight was investigated via simulation. It turned out that both light sources could decompose the cyanide in polluted soil and decrease the total cyanide and WAD cyanide with increasing treatment time. After 5 hours photolysis, UV ray could decrease total cyanide achieves by 24.76%, WAD cyanide by 18.89% while sunlight correspond- ingly drop by 33.87% and 13.52%.
