Определение массовой доли нефтепродуктов в почвогрунте по спектрам нарушенного полного внутреннего отражения

There was offered the method of measurement of petroleum products’ mass fraction by means of direct spectral approach, without preliminary samples handling as alternative to traditional approach. In this study were obtained spectrum of disrupted total internal reflection of pattern sample of clean and contaminated potting soil in the mean infrared band, at variation of oil and water content. By means of projection method on latent structures was developed a multidimensional calibrated model, which allows determine petroleum products concentrations from spectrum of disrupted total internal reflection. For assessment of modeling accuracy was applied method of cross-check (cross-validation). For adaptation given model to practical usage will be need its upgrading with new, including real samples, properties of which could be fluctuate in more wider limits then in pattern samples.
