摘　　要：讨论了重整原料油试样消解的前处理过程,提出了消解时间短、反应温和、重现性好的前处理方法,采用氢化物原子荧光光度法测定砷含量,检出限为0.02ng/mL。实验结果表明,该方法在灵敏度、重现性、分析速度,尤其是批量分析等方面具有卓越的表现。The pre-treatment process for counteraction of reforming material oil is discussed and the pre-treatment method with short counteraction time, temperate reaction condition and good repeatability is put forward. The content of arsenic is determined by atom fluorophotometry with detection limit of 0.02 ng/mL. The results show that the mentioned method has superiority in sensitivity, repeatability, analyse speed, especially in batch analyse.
