Method for simultaneously determining more than 38 elements in geological sample

The invention relates to the technical field of trace element determination, in particular to a method for simultaneously determining more than 38 elements in a geological sample. According to the method, a mixed acid solution is used as a digestion reagent, and a microwave digestion instrument and an inductively coupled plasma mass spectrometer are combined. According to the method, the tedious means that multiple times of pretreatment are needed and different instruments are used for independent determination when multiple elements in the geological sample are determined in the existing method procedure is simplified, the dosage of chemical reagents is reduced, the defect that the procedure of removing hydrofluoric acid through sample dissolution by an acid method is long in time consumption is overcome, and the detection efficiency is improved. 本发明涉及微量元素测定技术领域，具体涉及一种同时测定地质样品中38种以上元素的方法。该方法采用混合酸溶液作为消解试剂，将微波消解仪和电感耦合等离子体质谱仪相结合。该方法简化了现有方法规程中测定地质样品中多种元素时需要分多次预处理并利用不同仪器进行单独测定的繁琐手段，减少了化学试剂的用量，克服了酸法溶样赶除氢氟酸程序耗时长的缺点
