Description

Acetic acid is an organic acid widely utilized across food, chemical, pharmaceutical, textile, packaging and other industries. Due to high global demand, recovering and valorizing it from industrial waste streams presents an economically attractive alternative.1 Various methods exist for recovering acetic acid, including liquid-liquid extraction, reactive extraction, membrane extraction, and reactive distillation.2,3 However, to implement methods like reactive extraction, it is best to use activated carbon to clear the sample of any interfering compounds.4
The objective of the present study is to optimize the parameters of activated carbon filtration: carbon type, carbon amount, sonication time, filtration amount. Filtration efficiency was evaluated using Gas Chromatography-Mass Spectrometry (GC-MS) and capillary electrophoresis-UV. The primary target for filtration was furfural. The concentration of acetic acid was monitored using both analytical techniques to ensure if there were any losses. Preliminary results indicate that while activated carbon filtration is highly effective, the process requires further optimization. Visually, the treatment successfully transforms dark brown wastewater into a clear effluent. To minimize product loss and maximize efficiency, future work will focus on utilizing activated carbons specifically tailored for wood wastewater treatment.

Keywords: activated carbon, wood wastewater, GC-MS, CE-UV
