Study on Influencing Factors for Determination of Trace Heavy Metal Elements in Water
When analyzing trace heavy metals in water,appropriate containers,chemical reagents,and experimental water should be selected to effectively reduce systematic errors.This article experimentally demonstrates the purity of reagents,container materials,experimental water,and the treatment method of pinhole filters.The results show that using polypropylene containers,high-purity reagents,grade 1 water,and discarding the first 2 mL when filtering through a pinhole filter,introduces fewer impurities and less interference when detecting trace heavy metals,resulting in more accurate analysis results and more reliable data.
