利用土壤干燥箱主动干燥-微波消解-原子吸收分光光度法测定土壤中的重金属

摘要

The heavy metal in a large amount of soil sample could be determined in a short time by drying the soil with M280685 soil drying oven,microwave digestion and atomic absorption spectrophotometry.The qualified rate of the parallel double-sample testing by this method and the quality-controlled samples can both reach the requirements of Technical Specification for Soil Environmental Monitoring（HJ/T166-2004）.%利用M280685土壤干燥箱干燥土壤、微波消解、原子吸收分光光度法,在短时间内完成大量土壤样品中重金属的测定。利用该法测定土壤中的重金属平行双样测定合格率,质控样品均能达到土壤环境监测技术规范（HJ/T166-2004）相应的要求。
