Characterization and Analysis of Acetaldehyde Wastewater by Molecular Weight Distribution, Hydrophilicity, and Chemical Composition

Acetaldehyde is a typical toxic substance of the petrochemical industry. Dissolved organic carbon (DOC) plays an important role in wastewater treatment. Therefore, molecular weight, hydrophilicity, and chemical composition DOC acetaldehyde were evaluated. First, weight (MW) distribution was investigated; results showed that mainly composed components with MW less than 1 kDa, possessed higher proportion protein-like substances dominant contributors to membrane fouling. Then, hydrophobicity evaluated; hydrophobic bases reported be slowly biodegradable fractions due high humic content. Finally, gas chromatography–mass spectrometry (GC-MS) utilized determine composition, 30 pollutants detected. Aldehydes, hydrocarbons, ketones, alcohols, furans, phenols, acids pollutants. Most them moderately compounds. The comprehensive characterization will contribute control strategies sustainable development.
