Hydroxyapatite/Fe3O4 Nanocomposite as Efficient Sorbent for the Extraction of Phthalate Esters from Water Samples
In this study, we demonstrate the application of newly developed magnetic potassium substituted hydroxyapatite (KHA/Fe3O4) for the extraction of phthalate esters (PE) from water samples. Nanoparticles of KHA were synthesized through an easy alkoxide–based sol–gel technique. The structure of nanocomposite was characterized by X–ray diffraction (XRD), Fourier transform infrared (FTIR) analysis, a...
متن کاملPhthalate esters detected in various water samples and biodegradation of the phthalates by microbes isolated from river water.
Phthalate esters (PEs), especially di-n-butyl phthalate (DBP) and di-(2-ethylhexyl) phthalate (DEHP) were detected in various water samples such as river water, well water and tap water. On degradation tests of PEs, Tempaku River water degraded almost 100% of diethyl phthalate (DEP), di-isobutyl phthalate and DBP, and approximately 70% of DEHP. All eight isolates from Tempaku River water (R1-R7...
متن کاملExposure to phthalate esters.
The American Chemistry Council Phthalate Esters Panel read with great interest the paper by Blount et al. (1) regarding urinary levels of phthalate ester metabolites in a sample set of the Third National Health and Nutrition Examination Survey (NHANES III) population. We have known for some time of this research, and have provided whatever information and assistance we could to the Centers for ...
متن کاملCloud point extraction coupled with HPLC-UV for the determination of phthalate esters in environmental water samples.
A method based on cloud point extraction was developed to determine phthalate esters including di-ethyl-phthalate (DEP), di-(2-ethylhexyl)-phthalate (DEHP) and di-cyclohexyl-phthalate (DCP) in environmental water samples using high-performance liquid chromatography separation and ultraviolet detection (HPLC-UV). The non-ionic surfactant Triton X-114 was chosen as extraction solvent. The paramet...
متن کاملTesticular effects of phthalate esters.
The testicular effects produced by di(2-ethylhexyl) phthalate (DEHP) in the rat, characterized by a decrease in the relative organ weight and histological changes in the seminiferous tubules, can also be produced by di-n-butyl, di-n-pentyl and di-n-hexyl phthalates. The corresponding monoesters of these compounds, formed in vivo as a result of the action of nonspecific esterases in the intestin...
