A wavelength dispersive X-ray fluorescence spectrometry (XRP) method is described for the analysis of soluble chromium(V1) in chromium plating mist collected from workplace air. Calibration of the XRF for soluble chromium(VI) is achieved by using dibenzyldithiocarbamate chromium precipitates prepare
