土壤重金属污染普查样品加工的关键环节研究
Study on the Powdering of Soil Sample for Heavy Metal Pollution Investigation
摘要
Abstract
To solve the problem that there is no clear standard for the powdering of soil sample for heavy metal pollution investigation,meet the needs of modem analysis technology for heavy metals,this paper studied the impact of two key sections that are powdering mode and grain size on sample representativeness and processing efficiency.The results showed that the optimal powering mode was powder milling with agate milling.The grain size of soil sample should be less than 0.15 mm (-100 meshes) in the premise of confirming sample weight.The study proposed the processing flows of soil sample for heavy metal investigation based on relevant regulations,it can be used as reference for investigation work.关键词
