Application of zno nanowhiskers for the detection of p-hydroquinone

Highly dense ZnO nanowhiskers are obtained by the hydrothermal method and utilized as active working electrode material for the low level detection of phydroquinone. The morphological characterizations reveal that the synthesized nanomaterials exhibit the highly dense whiskers morphology with the average diameter of ~80-120nm. The synthesized ZnO nanowhiskers are crystalline, highly pure and possessed wurtzite hexagonal structure. ZnO nanowhiskers modified glassy carbon electrode (GCE) is used to fabricate the chemical sensor for the low level detection of phydroquinone. The fabricated chemical sensor attains substantially high sensitivity of ~99.2µA.µM ^-1.cm^-2, the limit of detection (LOD) of ~4.5µM, with a correlation coefficient (R) of ~0.98144.
