| 中文摘要: |
| 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。 |

| Five anions (F?, Cl?, NO2?, PO43?, NO3?) in Tricholoma giganteum fruiting body were determined by using ultrasonic assisted extraction (UAE)-ion chromatography (IC). After ultrasonic assisted extraction for 30min in NaOH solvent (3.0mmol/L), sample introduction as 100μL, Na2CO3+NaHCO3 (3.5mmol/L+1.0mmol/L) were chosen as washing solution with flowing rate at 1.2mL/min. The linearity ranges of 5 anions respectively were 2－25mg/L, 2－20mg/L, 2－100mg/L, 10－55mg/L, 10－100mg/L. The relative standard deviations (RSD) of the peak areas were 0.58%, 1.27%, 0.73%, 0.92%, 2.33%, respectively. The detection limits of the 5 anions were 0.0976－1.0984mg/L. The spike recoveries of 4 anions (F?, Cl?, PO43?, NO3?) were 95%－110%, whereas, the content of NO2? in T. giganteum was not detected out. |
