建立了微波消解-电感耦合等离子体质谱法测定甘蔗中25种元素的方法。确定了微波消解和电感耦合等离子体质谱仪的测量参数,该方法对各元素的检出限0.00090~6.19μg/g,相对标准偏差0.3%~2.5%,适用于甘蔗中多种元素的同时测定。
A microwave digestion - inductively coupled plasma mass spectrometry method for the determination of 25 elements in sugarcane was established. The parameters of microwave digestion and inductively coupled plasma mass spectrometry were determined. The detection limit of each element was 0.00090 ~ 6.19μg / g and the relative standard deviation was 0.3% ~ 2.5%, which was suitable for the simultaneous determination of various elements in sugarcane .
