Abstract

A green, rapid and sensitive high performance anion-exchange chromatographic (HPAEC) method for the determination of saccharin in environmental water samples is reported. A linear range of 5 μg/L to 28.2 μg/mL was found with a theoretical limit of detection of 5 μg/L based on a signal-to-noise ratio of three. No interferences were seen for sodium cyclamate, acesulfame K, aspartame, nitrite, nitrate and chlorate. Following a simple filtration sample pre-treatment a percentage recovery of 92.9 % and an associated coefficient of variation of 3.8 % was found for a sample fortified with 28.2 ng/mL saccharin. Separation was achieved within 2.5 minutes using a SAP 100 mm × 4.6 mm, 8 μm strong anion exchange analytical column with a mobile phase of 0.1 M NaCl at a flow rate of 1.5 mL/min. The develop method avoids the use of potentially environmentally hazardous reagents and minimises the production of waste.
