中文摘要: 基于HNO3-HF-HCl酸消解体系,建立微波消解-电感耦合等离子体发射光谱仪测定环境土壤中镧铈铷锶四种元素的方法。利用恒定的氩气流作内标校正土壤基体干扰,采用径向观测模式,利用多重谱线拟合技术(MSF)校正光谱干扰,提升本方法的检出限和精密度。结果表明：该方法校准曲线r>0.999,检出限在1.5~7.0 μg/g,RSD在0.9%~5.7%之间,加标回收率83.0%~117%,该方法用GSS-8、GSS-13标准样品验证,效果良好。
Abstract:Based on HNO3-HF-HCl acid digestion system, to established the new method to determine lanthanum, cerium, rubidium and strontium elements in the environmental soil samples by Inductively Coupled Plasma Optical Emission Spectrometry under microwave digestion instrument. Argon is used as internal standard to correct soil matrix interference. The detection limit and precision of the ICP-OES method were improved by means of using the radical observation mode and the multi spectral line fitting technique (MSF) to correct the spectrum interference. The calibration curve r>0.999, the detection limit of the method between 1.5~7.0 μg/g and RSD between 0.9%~5.7%, the recovery rate was 83.0%~117%. Using the new method to analysis the national standard soil samples of GSS-8、GSS-13, the determination of the value of each element is consistent with the standard value.
