dc.description.abstract | Waste cooking oils (WCO) recycling companies usually have economic losses for buying
WCO not suitable for biodiesel production, e.g., WCO with high free acidity (FA). For this reason,
the determination of FA of WCO by near infrared (NIR) spectroscopy was studied in this work to
assess its potential for in situ application. To do this, FA of 45 WCO was measured by the classical
titration method, which ranged between 0.15 and 3.77%. Then, the NIR spectra from 800 to 2200 nm
of these WCO were acquired, and a partial least squares model was built, relating the NIR spectra to
FA values. The accuracy of the model was quite high, providing r2 of 0.970 and a ratio of performance
to deviation (RPD) of 4.05. Subsequently, a model using an NIR range similar to that provided
by portable NIR spectrometers (950–1650 nm) was built. The performance was lower (r2 = 0.905;
RPD = 2.66), but even so, with good accuracy, which demonstrates the potential of NIR spectroscopy
for the in situ determination of FA of WCO. | es |
