Methods for Determination of Oil and Grease Contents in Wastewater from the Petroleum Industry
Infrared spectrometry and spectrofluorimetry methods were correlated in the measurement of oil concentration in produced water. Furthermore, we compared colorimetry and gravimetry techniques. Adsorption experiments were performed in synthetic oily wastewaters by polymer compounds based on poly(hydroxyethyl acrylamide and polypropylene. The residual oil content was used in the techniques correlation.
