Rapid method for the determination of moisture content in biodiesel produced from insect’s oil using FTIR spectroscopy

Rapid method for the determination of moisture content in biodiesel produced from insect’s oil using FTIR spectroscopy

A new, rapid, and direct method was developed for the determination of moisture content in biodiesel produced from insects’ oil using Fourier transform infrared (FTIR) spectroscopy with Attenuated total reflectance (ATR) element. The calibration set was prepared by spiking double distilled water in...
