General description

The microbial degradation of tributyl phosphate was carried out using Klebsiella pneumoniae S3 isolated from the soil. The solubilization behavior of TBP in aqueous solutions was studied using light and small angle neutron scattering (SANS).

Tributyl phosphate (TBP) is an organophosphate compound widely used as an extraction solvent, flame retardant, and plasticizer.

Application

Tributyl phosphate (TBP) was used as defoamers and/or plasticizers, in fuel reprocessing and extraction.
