    Abstract: Many types of Soils are contaminated by
Total Petroleum Hydrocarbons (TPH) as Mixture from it.
This study depend on Idea that contaminated soil contain
range of TPH with UV absorbance corresponding to TPH
contents. Using range of TPH from different
hydrocarbons contaminated soil sites as mixture standards
sample as an easy, adequate and accurate methods for
determination of TPH in any soils. The results
demonstrate the absorption tip was constant at 240 and
210 nm for the MSS solute in CH<sub>2</sub> Cl<sub>2</sub> and hexane and
there is a linear relation between the concentrations of
MSS and identical UV absorbance fitted, CH Cl (r =
0.9977) and hexane (r = 0.996).
