HJ 702-2014 (English Version) PDF

Scope: This standard specifies the microwave digestion/atomic fluorescence determination method for mercury, arsenic, selenium, bismuth and antimony in solid waste and solid waste leachate. This standard is applicable to the determination of mercury, arsenic, selenium, bismuth and antimony in solid waste and solid waste leachate. When the solid waste sample size is 0.5g, the detection limit of mercury in this method is 0.002µg/g, and the lower determination limit is 0.008µg/g; the detection limit of arsenic, selenium, bismuth and antimony is 0.010µg/g, and the lower determination limit is 0.010µg/g. 0.040µg/g. When the solid waste leachate sampling volume is 40 ml, the detection limit of mercury is 0.02 μg/L, and the lower determination limit is 0.08 μg/L; the detection limits of arsenic, selenium, bismuth, and antimony are 0.10 μg/L, and the lower determination limit is 0.40 μg/L.
