Modified dispersive solid-phase extraction of benzophenones and parabens from water samples using nutshell-derived biochars: development, validation and greenness assessment.
A simple, fast, and eco-friendly modified dispersive solid-phase extraction (dSPE) method was proposed for the determination of benzophenones and parabens in water samples using biochars derived from nutshells (walnut, hazelnut, peanut, and pistachio shells). Biosorbents were characterized by FTIR, SEM, and BET analyse...
