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 (100-300 mg/L) while, the equilibration time (25 min) was independent of initial NO3- concentration. The breakthrough capacities in Milli-Q and tap water were 35 and 30 mg/g, respectively. (C) 2013 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V.
