摘　　要：本文使用岛津ICPMS-2030电感耦合等离子体质谱仪,采用微波消解法对锰结核样品进行前处理,测定了锰结核样品中32种元素含量.实验结果表明,各元素在1.0—100μg·L^(-1)范围内线性关系良好,相关系数均大于0.9998,检出限低,各元素检出限都在0.00004—0.73μg·g^(-1)之间.该方法操作简便、快速,测试结果准确,使用锰结核标准物质GBW07296进行验证,测定值与标准值基本吻合,该方法可适用于锰结核样品中多元素含量的测定.A method for determination of thirty-two multi-elements in manganese nodules was developed by using inductively coupled plasma mass spectrometry(ICPMS-2030) of Shimadzu Company. Samples were dissolved by microwave digestion. The experimental results show that the correlation of coefficients were above 0.9998 in the range of 1.0 —100 μg·L^(-1), the detection limit of each element is between 0.00004—0.73 μg·g^(-1). The method is simple and convenient. The manganese nodules reference material GBW07296 is used for verification, and the measured value is basically consistent with the standard value. This method is applicable to the determination of multi-elements in manganese nodules.
