| Abstract | ||
| A new method was developed for determination of hexavalent chromium using bifunctional ion exchanger by ion chromatography with UV detection. The method was optimized against the eluent pH, concentration and flow rate using certified soil sample (NCS DC 73325). The detection limit achieved was about 0.01 mgL -1 with relative standard deviation of 0.048%. The developed method has been applied for the determination of Cr(VI) in three geological materials. However, this paper presented simple determination of Cr(VI) in various materials without prior technological methodologies of separation of the ion concentrate which plays an important role in high accuracy sample determinations | ||
