Abstract:

This study investigated the measurement of free cyanide in liquor by ion chromatography coupled with pulsed amperometric detection (IC-PAD). Eluent concentration, interferent evaluation and method performance were discussed. Results show that free cyanide in liquor can be rapidly determined by the optimised IC-PAD method. A sample requires only 1:100 dilution and simple filtration before being subjected to IC-PAD. The linear range is 1-5000 μg/L with an R value of 0.9998. The detection limit is 1 μg/L for a 25 μL injection loop. The overall relative standard deviation (RSD) of the method is less than 5%, and the recovery range is from 98.1% to 105.0%. This study has been proven significant and may have potential applications in liquors analysis.
