  ABSTRACT: This study presents a novel and facile technique for the rapid and sensitive detection of zinc (Zn) in foods and drinking water. The need for a reliable method to monitor Zn levels in consumables is crucial due to its significance in both nutritional assessment and environmental safety. The proposed technique integrates state-of-the-art sensing technology with an easy-to-implement approach, aiming to provide an efficient solution for Zn detection. The methodology involves the utilization of complexation of Zn2+ ion with resorcinol and use of UV-vis spectrophotometry, which demonstrates high sensitivity towards Zn2+ ions. It detected zinc up to 10-5M solution.
