摘要
采用过氧化钠碱熔的前处理方法,阳离子交换树脂分离—电感耦合等离子体质谱法同时测定碘、硼、锗、锡、砷、磷、钼和钽,对实验参数进行了考察,确定了最佳条件。结果表明,碘、硼、锗、锡、砷、磷、钼和钽标准曲线的相关系数均>0.9990,检出限分别为0.2μg/g、1μg/g、0.06μg/g、0.2μg/g、0.2μg/g、10μg/g、0.1μg/g和0.01μg/g,测定结果的准确度均小于0.1,精密度均小于10%,满足DZ/T0258—2014《多目标区域地球化学调查规范(1∶250000)》。
The pre-treatment method of sodium peroxide base melting and the cationic exchange resin separation- inductively coupled plasma mass spectrometry were used to determine the elements of iodine,boron,germanium, tin,arsenic, phosphorus,molybdenum and tantalum.Various experimental parameters were examined and the optimum parameters were determined.The results show that the correlation coefficient of the standard curve of iodine,boron,germanium,tin,arsenic,phosphorus, molybdenum and tantalum was all >0.999 0,the detection limits were 0.2 μg/g, 1 μg/g,0.06 μg/g,0.2 μg/g,0.2 μg/g,10 μg/g,0.1 μg/g,0.01 μg/g,respectively.The accuracy was below 0.1 and the precision was below 10 %, meeting the requirement of DZ/T 0258-2014 Specifications for Multi-purpose Regional Geochemical Survey(1 ∶ 250 000).
