The conductivity was enhanced by addition of dibutyl phthalate (DBP) plasticizer and ZrO2nanofiller with maximum conductivity(1.38×10-4 Scm-1). The absorption edge and band gap values showed decreases upon addition of LiSO3CF3, DBP, and ZrO2due to the formation of localized states in the SPE and the degree of disorder in the films increased.

At least one sample from the same manufacturer and colour, was identified and analyzed for dibutyl phthalate (DBP). GC/MS method was developed for the identification and quantification of dibutyl phthalate in water-based paints after solvent extraction. The highest level of DBP found was 47,100 ppb (unregistered manufacturer), followed by 45,100 and 19,400 in a white, pink and cream coloured paint, respectively, while the lowest concentration was 721 ppb in a cream coloured paints, unregistered m

Based on analysis of the 16S rRNA gene, the strain was identified as a representative of the genus Rhodococcus. Strain 5A-K4 had the highest level of the 16S rRNA gene similarity (99.86%) with Rhodococcus erythropolis NBRC 15567T. The strain grew effectively on a DBP substrate without

Abstract—The ability of the white rot fungus Peniophora lycii to degrade such phthalic acid esters (PAEs) as diethyl phthalate (DEP), dibutyl phthalate (DBP), di(2-ethylhexyl) phthalate (DEHP), diisobutyl phthalate (DiBP), and n-butylbenzyl phthalate (BBP) was studied. It was shown that DEHP was most efficiently biodegraded by the fungus (over 98% on day 6 of cultivation). The residual content of DBP and DiBP in the culture liquid of the fungus at the end of cultivation (10 days) was ~17–18%. BBP turned out to be the most difficult-to-degrade compound: its residual content on day 10 of P. lyci

Dibutyl phthalate (DBP) is widely used as a plasticizer in the production of polymeric materials to give them flexibility, strength and extensibility. However, due to its negative impact on human health, in particular reproductive functions and fetal development, the content of DBP must be controlled in food and the environment. The present study aims to develop a sensitive, fast and simple fluorescence polarization immunoassay (FPIA) using monoclonal antibodies derived against DBP (MAb-DBP) for its detection in open waters.
