陕西煤中汞的含量分布及赋存状态研究
Study on the distribution and occurrence state of mercury content in Shaanxi coal
摘要
Abstract
Mercury emissions caused by coal combustion can cause harm to the environment and human health.Re-moval of mercury before coal combustion is an important way to reduce the environmental pollution caused by mercury.Therefore,analyzing and studying the distribution and occurrence of mercury content in Shaanxi coal can provide data support for environmental management in mining areas within Shaanxi Province,which is of great significance for ef-fectively reducing the environmental pollution caused by mercury in coal and the potential harm to human health.347 batches of samples from 206 coal production enterprises in Shaanxi Province were taken,and the mercury content in coal samples was determined by GB/T 16659-2008 cold atomic absorption spectrophotometry.The mercury content and occurrence state in Shaanxi coal were studied by analyzing and statistically analyzing the detection data.The dis-tribution range of mercury content in Shaanxi coal is 0-0.735 μg/g,with an average value of 0.059 μg/g;statisti-cal analysis of the correlation between mercury and total sulfur,ash content,arsenic,fluorine,chlorine,and phos-phorus in Shaanxi coal shows that mercury mainly exists in the form of pyrite,with low correlation with arsenic and fluorine elements,and no correlation with phosphorus and chlorine elements.关键词
