文摘

Four silicone oils (PolyDiMethylSiloxane, PDMS) of different viscosities, namely 5, 20, 50, and 100 mPa s were characterized to select the most suitable polymer for the biological treatment of toluene. The PDMS volatilities and the partition coefficients of toluene between air and PDMS were investigated. Toluene biodegradation tests were also carried out to assess the absence of toxicity of the considered PDMS vis-a-vis the microorganisms.
