%X 采用超声波（UAE）辅助提取-离子色谱（IC）法测定了大白口蘑中F?、Cl?、NO2?、NO3?、PO43? 5种阴离子。选用NaOH溶液（3.0mmol/L）超声渗提30min后进样100μL，通过流速为1.2mL/min的淋洗液Na2CO3+NaHCO3（3.5mmol/L+1.0mmol/L）洗脱。F?、Cl?、NO2?、NO3?、PO43? 5种离子线性范围分别为2－25mg/L、2－20mg/L、2－100mg/L、10－55mg/L、10－100mg/L，峰面积RSD分别为0.58%、1.27%、0.73%、0.92%、2.33%，检出限在0.0976－1.0984mg/L之间。大白口蘑样品中未检出NO2?，其余F?、Cl?、NO3?、PO43? 4种离子加标回收率在95%－110%之间。
