Determination of lead, cadimi, chromium and arsenic in synthetic resin emulsion coating of interior wall by X-ray fluorescence spectrometer EDX8000B

Determination of lead, cadimi, chromium and arsenic in synthetic resin emulsion coating of interior wall by X-ray fluorescence spectrometer EDX8000B

The contents of Pb, CD, Cr and As in synthetic resin emulsion coating wall were determined by bench high resolution energy dispersive X-ray fluorescence spectrometer EDX9000A and quantified by external standard method. The working curves of the above four elements were made with the simulated sample as the matrix, and the mass fraction of the four elements had a linear relationship with their fluorescence intensity in the range of 100 trang/phút. The results of real samples show that the results of this method are consistent with those of inductively coupled plasma atomic emission spectrometry when the content of the above four elements is greater than 5ppm.
