Abstract

The adsorptive potential of De-Acidite FF-IP resin for the removal of nitrate (NO3−) from synthetic as well as commercially available bottled water samples was testified. Ultra-performance liquid chromatography–mass spectrometry (UPLC–MS) was utilized for detection and determination of NO3−. Optimum NO3− adsorption was observed at pH range 2 to 6. Kinetic studies revealed the applicability of pseudo-first-order kinetic model for analyzed concentration range (100–300mg/L) while, the equilibration time (25min) was independent of initial NO3− concentration. The breakthrough capacities in Milli-Q and tap water were 35 and 30mg/g, respectively.
