摘要: A laboratory study was conducted to enhance removal of residual contaminants after composting in a highly petroleum-contaminated soil by combining Fenton-like pretreatment with biodegradation. The were characterized Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) during treatment. optimum molar ratio H(2)O(2) and Fe(3+) 300/1 determined batch experiments. At the end treatment, total dichloromethane-extractable organics (TEO) decreased from 32,400 21,800 mg kg(-1) soil, toxicity reduced greatly preoxidation process. significant loss number microorganisms observed reaction. During microbial treatment period, 50.6% TEO destroyed. Numerous varieties polar compounds containing nitrogen oxygen identified FT-ICR MS. two atoms dropped 604 163 oxidation, increased again 577
