Organic compounds in solidified petroleum sludge and leachate

Petroleum sludge was solidified in ordinary Portland cement, and the leachability test performed based on ANS 16.1 to produce leachate. The organic in solidified sludge was extracted by micro solid extraction to determine the organic in the sample. Organic in the leachate sample was detected by solid phase micro extraction by head space PDMS fiber using the GCMS. The targeted organic content in solid sample and leachate was quantified by the BTEX, naphthalene and phenanthrene standard. The organic in solidified sludge consist of aliphatic and ester acid formed by C15 to C64. The aliphatic group in the leachate was found at the reduced rate of about tenfold of the solid sample. Derivative leachate products mainly composed of cyclic siloxane compound.
