Estimation of Some Carboxylic Acids and Inorganic Anions in Industrial Fruit Juice Beverage by Ion Chromatography


conductivity detection at baseline ≈0.05 μs cm-1 of complex formed with the Dionex IonPac AS11-HC-5 μm Column. This method,high speed, efficient, cheap,very Recoveries and isocratic phase. Method has been developed and validated for the Estimation of Organic acid and anions using 5 mM sodium hydroxide as mobile phase having PH 9 Mobile phase was pumped at flow rate of 1.0 mL min-1 and isocratic elution using through column. The Conductivity detection method was performed at 12 minutes. Method was successfully following the IC Isocratic. Calibration curve was very linear in concentration range [(2-10) and (3-15)] μg mL-1 for Chloride and Phosphate Consecutively with correlation coefficient Range R2(0.9890-1.0) for inorganic anion and Calibration curve (5-25) μg mL-1 for each carboxylic acid but non-linear (n=3). The determine of lower limits of detection (LLOD) and quantitation (LLOQ) in standard Analyzed for inorganic anions, Also; method detection limit (MDL) for each anion in Organic acids. Recovery was found to be in the range 96.6-101.3% and precision less than 1%. Developed method was validating applied for analyzed of standard solution and also to study the interaction of Analysis at room temperature.
