      Objective To establish a method for the determination of 18 metal elements including Al、As、B、Ba、Cd、Cr、Cu、Fe、Hg、Mn、Ni、Pb、Se、Sn、Sr、Ti、Zn、Sb in citrus peel by inductively coupled plasma mass spectrometry. Methods Through microwave digestion and on-line internal standard correction by inductively coupled plasma mass spectrometry. The interference by built-in kinetic energy discrimination mode was eliminated. The linear range, detection limit, precision and recovery rate were verified. Result The linear range of the method was 10?100 μg/L, the detection limit was 0.0001?0.4202 μg/L, the rate of recovery was 83.0%?107.4%, and the relative standard deviation was 0.61%?3.62%. Conclusion This method is simple, rapid and accurate, which is suitable for the simultaneous determination of multiple elements in citrus peel.
