Study on the distribution pattern of PAHs in the coking dust from the coking environment

摘要：

　　This paper conducts a study and analyzes five kinds of dust samples of different environment,including an office area,a ground station of the new plant,the first workshop of coking,a top of coke oven and a ground station of the old plant in coking plant and obtaines the distribution pattern of PAHs in the coking dust by the way of ultrasonic extraction and high performance liquid chromatography.The data show that PAHs from the first workshop turns out to be the richest with its content getting up to 12.00 μg·m-3.By analyzing the single component distribution of PAHs,the results show that there are fourteen kinds of PAHs produced at 5 sites.Through analyzing the particle size of coking dust,its size is mainly below 10μm and its contents exceeds to 75%.The first workshop environment is the highest and reaching 98.39%.
