Study on the Accurate Determination of Polycyclic Aromatic Hydrocarbons in Coal Tar Utilization

Abstract:

The determination of polycyclic aromatic hydrocarbons (PAHs) in coal tar was systematically studied by the high performance liquid chromatography (HPLC), in which involved separation, qualitative and quantitative determination of PAHs. The series of key techniques and experiences were summarized. To ensure finely separation of PAHs PAH, using C18 bonding silica gel column, mobile phase of methanol-water, and theoretical plate number of column more than 5600 were needed. For quantitative determination, the external standard (E-X) quantitative method and external standard - response factor (E-F) quantitative method were recommended. For accurately quantitative determine PAHs, the key technologies were recommended including choice of the optimum solvent of samples preparation and optimum concentration and using ultrasonic treatment, etc. In addition, some determination typical coal tars were also given and recommended. .
