Attenuated Total Reflectance Fourier transform infrared spectroscopy for determination of Long Chain Free Fatty Acid concentration in oily wastewater using the double wavenumber extrapolation technique
A novel Double Wavenumber Extrapolative Technique (DWET) was developed. The DWET was used to measure both LCFFAs and FOG concentration in oily wastewater. The DWET showed satisfactory accuracy and was validated using GC measurements.
