Abstract
The present study demonstrates, a selective detection of Fâ using aluminium (Al) micro-interdigitated electrode (μ-IDEs) array modified by graphene oxide (GO). The selectivity of the fabricated sensor towards Fâ in presence of contaminants like, Chloride (Clâ), Bromide (Brâ) & Nitrate (NO3â) at concentration of 100 and 50 ppm is investigated using simple electrical measurements. The selectivity of GO/Al-μ-IDEs is attributed to the highest electro-negativity and strong affinity of Fâ towards Al. The real time, cost effective, selective GO/Al-μ-IDEs based molecular sensors shows the potential for detection of aqueous Fâ in presence of other contaminants.
