Dispersive Solid-Phase Extraction of Methyl, Ethyl, Propyl, and Butyl Parabens byMnO۲@tea polyphenols

The MnO۲@tea polyphenols used as a sorbent in dispersive solid-phase extraction (DSPE) of methyl,ethyl, propyl, and butyl parabens from wastewater and cosmetic samples followed by HPLC-UV. Afteroptimization using response surface methodology, the linearity and limits of detection were in the range of ۰.۱-۵۰۰ μg/L and ۰.۰۸-۰.۳ μg/L, respectively
