Article Synopsis
- The rising demand for clean energy and the negative environmental effects of fossil fuels have led to increased use of renewable energy sources, including biomass and thermal processes.
- The study provides a detailed chemical analysis of sludges from domestic and industrial wastewater treatment and the bio-oils produced through fast pyrolysis, using several advanced characterization techniques.
- The results indicate that while bio-oils contain a significant amount of nitrogenous compounds, making them unsuitable as renewable fuels, they have potential for recovery processes to produce valuable products like fertilizers and surfactants.
In this study, a comprehensively optimization of QuEChERS (quick, easy, cheap, effective, rugged and safe) method using design of experiments (DOE) was conducted to evaluate the best conditions to obtain the most effective extraction. Liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) analysis was performed to identify and quantify the antidepressants, with electrospray ionization acquired in positive mode. The method was validated for all analytes; the calibration curves were linear from 10-1000ng/mL, with R>0.
