Selective electrochemical detection of hydroquinone and catechol at a one-step synthesised pine needle-like nano-CePO₄ modified carbon paste electrode

Abstract

A pine needle-like nano-CePO4 modified carbon paste electrode was successfully constructed for simultaneous detection of hydroquinone and catechol sensitively and selectively.

Electrochemical Sensing Platforms of Dihydroxybenzene: Part 2 – Nanomaterials Excluding Carbon Nanotubes and Graphene

“…Due to the occupation of 4 f shells in their ions, rare earth compounds exhibit unique chemical, optical and electrical properties. Dang et al [113] . used the precipitation method to synthesize pine‐needle‐like CePO 4 nanomaterials.…”

Facile synthesis of flower-like CePO4 with a hierarchical structure for the simultaneous electrochemical detection of dopamine, uric acid and acetaminophen

“…17 Zhou et al reported a pine needle-like CePO 4 nanomaterial for the determination of catechol and hydroquinone. 18 Electrochemical responses were significantly improved over a CePO 4 modified electrode because of the largely improved specific surface area. Feng et al reported a CePO 4 nanotube modified electrode for hydroquinone sensing.…”

A highly sensitive and selective hydroquinone sensor based on a newly designed N-rGO/SrZrO3 composite

“…5 Even trace amounts of HQ may also cause hypoesthesia, puking, debility, fatigue, kidney damage and headache. [6][7][8][9] HQ is widely used in cosmetics for bleaching purposes but long-term/ excessive use may be responsible for skin damage or severe allergy. 6 Thus, a sensitive and reliable method is required to detect trace levels of HQ.…”
