Sensitively-selective determination of Propyl Paraben preservative based on synergistic effects of polyaniline-zinc-oxide nano-composite incorporated into graphite paste electrode.

The application of Propyl Paraben (PP) as a chemical preservative has expanded and diversified. Widespread use of products containing PP has resulted in its ubiquitous occurrence in environment and biological fluids among the general population. Several in-vivo studies have associated PP with estrogenic activity and malfunctioning of reproductive organs.

An electrochemical Bisphenol F sensor based on ZnO/G nano composite and CTAB surface modified carbon paste electrode architecture.

Due to the enforcement of regulatory restrictions to prevent risk to human health from Bisphenol A (BPA), its structural analogue Bisphenol F (BPF) has been introduced into the market as an alternative. But however recent studies describe BPF as an effectual endocrine disruptor. Hence, there is an indispensible need for research concerning BPF human and environmental exposure level.
