The water,HNO3 (0.15 mol/L)and HCl (0.12 mol/L) as the extraction reagent,using microwave ex-traction as pre-treatment,determination of arsenic species in rice by IC-ICPMS. Finally,discussed and summa-rized the different pretreatment methods and solvents at different temperatures and time on the measurement re-sults,analyzed and summarized the differences of different methods by compared with the other two standard methods,GB 5009.11-2014and GB/T 23372-2009.%以纯水、硝酸溶液（0.15 mol/L）、盐酸（0.12 mol/L）作为萃取试剂，采用微波萃取作为前处理，通过离子色谱和电感耦合等离子体质谱联机法测定稻米中砷的形态。比较和总结了不同前处理方法和溶剂在不同温度和时间下对测量结果的影响，同时将本文测定方法与GB 5009.11-2014《食品安全国家标准食品中总砷及无机砷的测定》、GB/T23372-2009《食品中无机砷的测定液相色谱-电感耦合等离子体质谱法》两个国标方法做了对比，对不同检测方法的差异性进行分析和总结。
