Abstract
ABSTRACT An inductively coupled plasma optical emission spectrometry (ICP OES) method for Pb, Zr, Ti, Sr, Cr, Fe, Cu, Mn, and Al determination in PZT-ceramics is described. Careful analytical work was carried out in order to evaluate precision, accuracy, and matrix interference. Different procedures were investigated for the ceramics decomposition. Axially viewed plasma operating conditions were evaluated for trace elements (Al, Fe, Cu, Mn, and Cr) in presence of sample matrix. The relative standard deviation (RSD) ranged from 0.7 to 3.9%, whereas the analytes recoveries in the spiked samples ranged from 92 to 119%. The detection limits (LODs) of trace elements ranged from 2.4 to 2.6 µg g−1. The developed method is useful for evaluating the PZT-ceramics synthesis.
