[PDF] Determination of Total Petroleum Hydrocarbon TPH and Polycyclic
Abstract In the analysis of petroleum hydrocarbon contaminated soils for total petroleum hydrocarbons TPHs and polycyclic aromatic hydrocarbons PAHs the roles of spectroscopic and nonspectroscopic techniques are inseparable Therefore spectroscopic techniques cannot be discussed in isolation In this report spectroscopic techniques including Raman fluorescence infrared and visible
