微波萃取法提取紫菜中无机砷,利用正交试验设计法优化无机砷的微波最佳提取条件为:温度80℃,萃取时间30 min,微波功率1200 W.在最佳微波萃取提取条件下与国标GB 5009.11-2014《食品安全国家标准食品中总砷及无机砷的测定》方法对比测得紫菜中无机砷含量具有一致性.%Orthogonal experiment was used to optimize microwave extraction of inorganic arsenic from laver. Results showed that the best extraction conditions:80℃, 30 min, and 1200 W of microwave power. In the best condition of microwave extraction to extract compared with national standard GB 5009.11-2014 method mea-sured content of inorganic arsenic in laver was consistency.
