【摘要】 阐述了少量样品与微晶纤维素混合，直接压片成型后测定其中的砷，采用经验系数法校正基体效应。分析范围为０．１１～３１．０３％，砷含量１６．０２％时，方法的相对标准偏差为２％，分析结果与化学法相符。更多还原

【Abstract】 fast determination method for arsenic in multimetal mineral sample by XRF has been developed.A little amount of sample is mixed with microcrystalline cellulose,then directly pressed into disc.The empirical coefficient method is applied to correct matrix effects.The analysis range is 0.11～31 03%.When the arsenic content is 16.02%,the RSD is 2%.The results of XRF agree with those of chemical analysis.更多还原
