Determination of the contents of Cr(VI) stripped from ceramic cartridge faucets - Liquid chromatography - inductively coupled plasma-mass spectrometry

In this experiment, ammonium nitrate as mobile phase, by complexing Cr(III), under alkaline conditions, to achieve the separation of Cr(VI) and peak in front, LC-ICP-MS method was established for determination precipitation faucets. The had a good linearity range 1~10 μg/L. And suitable small volume faucets due amount extracting liquid low detection limit.
