The critical step in the analysis of this pigment is the conversion of the solid sample to a representative solution. This study compared four acid decomposition procedures for TiO2 for the determination of Al, P and trace impurities using inductively coupled plasma optical emission spectrometry. The decomposition procedures investigated involved acid digestion with: (i) (NH4)2SO4/H2SO4; (ii) HF/H2SO4; (iii) H3PO4; and (iv) HCl/HNO3/HF. This latter mixture was tested in a microwave-assisted procedure with closed vessels. Comparing the procedures using conventional conductive heating, the procedure using (NH4)2SO4/H2SO4 was the most suitable for complete decomposition of TiO2 samples, requiring approximately 30 min. Applying a paired t-test, it was shown that all strategies led to results in agreement at a 95% confidence level with those obtained using X-ray fluorescence. The accuracy for Cr, Fe, P and Zr was also checked using a certified reference material, and again all results were in agreement at a 95% confidence level. The performance of two ICP-OESs, one based on a mini-torch using a radial view configuration, and the other based on an axial view configuration, were compared. Both plasmas are intensely affected by matrix constituents. The mini-torch plasma is less able to cope with high amounts of solids; however this parameter also negatively affects the background level when using axial-viewed ICP-OES.Submitted by Suelen Reis (suelen_suzane@hotmail.com) on 2012-12-17T16:01:24Z No. of bitstreams: 1 1-s2.0-S0026265X01001199-main.pdf: 235134 bytes, checksum: 30e4fa2bba2eef9c1cd98940fbbaeda1 (MD5)Made available in DSpace on 2012-12-17T16:01:24Z (GMT).
