摘要
建立了微波消解-石墨炉原子吸收测定土壤中钒的方法,优化了微波消解程序。方法在0μg/L^100μg/L范围内线性良好,以称样0.500 0 g、定容体积50 mL计,方法检出限为0.2μg/g,环境土壤标准样品测定的RSD为2.5%,加标回收率为92.0%~104%。
The determination method of vanadium in soil was established by microwave digestion -GFAAS. The microwave digestion process was optimized. The linearity from 0 μg/L to 100 μg/L was good. The detection limit was 0.2 μg/g by 0. 500 0 g soil sample and the volume capacity of 50 mL, the RSD 2.5% and the recoveries from 92.0% to 104% in the environmental standards soil samples test.
