Abstract
This paper presents a validation study on the determination of gaseous mercury in exhaust gas from stationary pollution sources using HJ 917-2017,Stationary source emission-Determination of total gaseous mercury-Carbon sorbent traps/thermal cracking atomic absorption spectrophotometric method.The validation primarily encompasses the following components:a whole-process blank test,a standard curve test,limit of detection(LOD)and limit of quantitation(LOQ)tests,precision tests,accuracy tests,and actual sample measurements.The results of the aforementioned measurement indicators reveal that:the measured values of the whole-process blanks are all below the LOD of the method;the correlation coefficient of the standard curve is 0.9994;the LOD is 0.04 μg/m³;the LOQ is 0.16 μg/m³;the precision ranges from 0.13%to 0.66%;the accuracy lies within-2.90%to-1.02%;the spiked recovery rates for actual samples are between 99%and 113%;and the penetration rates are 12.7%to 18.6%.All the above-mentioned performance indicators satisfy the requirements stipulated in the method standard,indicating that the laboratory possesses the capability to determine gaseous mercury in exhaust gas from stationary pollution sources using the carbon sorbent traps/thermal cracking atomic absorption spectrophotometric method.关键词
