| 摘 要： | 用不同的消解方式处理试样松口蘑(SKM 20080604),电感耦合等离子体-原子发射光谱法(ICP-AES)测定松口蘑中铝含量。该方法具有灵敏度高、检出限低、精密度好、效率高等优点,其检出限为0.18mg·mL-1,RSD为1.96%。若使用超声雾化器雾化装置,检出限为0.05mg·mL-1,RSD为5.49%。采用硫酸消解方式,能够明显提高松口蘑的消解效率;样品的酸度过高会影响测定结果,样品中硫酸含量低于2.5%以下时,可得到满意的结果。同时,可用该分析方法测定美味牛肝菌、大白口蘑中的铝。

| Abstract: | Aluminum element in tricholoma matsutake(SKM 20080604)was digested by different digestion methods,and determined by inductively coupled plasma-atomic emission spectrometry.The detection limit is 0.18mg·L~(-1) and RSD is 1.96%.This method is sensitive,lower limits of detection,effective and stable.With ultrasonic atomized implementation,the detection limit is improved as 0.05mg·L~(-1),RSD is 5.49%.The digestion efficiency of high protein in edible fungi (T.matsutake)by vitriol can be improved.Hyperacid sample solution results in bad recoveries.When the amount of vitriol in the sample solution is less than 2.5%,good results are obtained. |
