| 摘 要： | 利用分光光度法测定了铊在硫铁矿焙烧灰、渣中的含量，探讨了含铊硫铁矿燃烧后铊在灰渣中的集散规律及其对环境影响。结果显示硫铁矿焙烧灰渣中铊含量远高于克拉克值和土壤背景值；与原矿石相比，铊在炉灰中富集，炉渣中含量减少。硫铁矿燃烧产生的含铊灰渣对环境危害增大。

| Abstract: | WT5BZ]In this paper, the content and distribution of thallium in pyrite ash and cinder are studied. The accumulation and scatter laws and the environmental effects of thallium in pyrite cinder are also approached. The study shows that the contents of thallium in pyrite cinders are obviously higher than the Clark value and soil background values. Comparing with the content of thallium in pyrite ores, the content of thallium increased in fly ash, but decreased in bottom ash. The pyrite cinders have more dangerous effects on environment than pyrite ores. WT5HZ] |
