１引言 煤是我国的主要能源，经燃烧炉排放的砷，硒等易挥发元素对大气产生较严重污染但因煤的成分复杂特殊，且砷，硒含量较低，试样处理及分析测试均较困难。本文研究使用了烧结分解法分解砷，湿法 ＨＦ＋ ＨＮＯ３＋ ＨＣｌＯ３分解硒后采用氢化物－电感耦合等离子体发射光?
1 Introduction Coal is the main energy source in our country. The volatile elements such as arsenic and selenium released from the combustion furnace produce more serious pollution to the atmosphere. However, due to the complicated composition of coal and the low content of arsenic and selenium, the samples are treated and analyzed More difficult. In this paper, the decomposition of arsenic by sintering decomposition was studied. Hydride-inductively coupled plasma was used to emit light after HF + HNO3 + HClO3 was decomposed by wet method.
