Abstract:This paper reported the method for the determination of Si, P, Cu, S, Mn, As, Ti, Sn, V, Cr, Ni, Mo and Al in cast iron by X-ray fluorescence (XRF) spectrometry with power pressed method. The sample was pretreated with low-temperature annealing method, and during the sample-molding process, ten drops of mixed solution with certain ratio of rosin and acetone in the adhesive layer. The method selected fifteen national/ministerial grade and self-made standard samples to prepare a standard series of sample for establishing the calibration curve. The blank sample coefficient correction method was employed for calibrating the interference resulted from the overlaps of spectrum lines. Theoretical alpha coefficient and empirical coefficient was combined to overcome the sample spectral interference and matrix effect. The results of the proposed method were consistent with those of inductively coupled plasma spectrometry and spark source optical emission spectrometry.
