A simple method has been developed for the determination of trace toxic elements like arsenic, lead and chromium in titanium dioxide pigment samples by ICP OES attached with a Concomitant Metals Analyser. Open mineral acid decomposition was used for sample dissolution employing a mixture of nitric and hydrofluoric acids. The continuous online generation of hydrides into the plasma was achieved through a concomitant metals analyser. The recovery of arsenic, lead and chromium and the matrix effects of titanium on these elements have been studied with spiking experiments. The proposed method has been successfully applied to the determination of arsenic and other elements in titanium pigment samples. The continuous hydride generating system, Concomitant Metals Analyser (CMA) improved the sensitivity of analysis nearly five times in pigment samples. The precision of the measurements was found to be less than 10% RSD.

A fast and simple method to allow routine analysis of waste phosphors was developed and fully validated. Pb, Hg in waste fluorescent lamps phosphors (WFP) and Pb, Cd in waste CRT phosphors (WCP) were quantified by inductively coupled plasma atomic emission spectrometry (ICP-OES). Analytical conditions, including choice of analytical spectral lines, sample dissolution methods and many other standards, were studied. Wavelengths of 220.353, 228.802, and 184.886 nm were selected as analytical lines for determination of Pb, Cd, and Hg respectively. Studies showed that, Nitric acid could be used for dissolving Cd and Hg, and alkali fusion method for Pb. Detection limits of Pb, Cd, and Hg found were 1.8, 0.3 and 3mg/kg respectively. The proposed method was used in determination of target elements in waste rare earth phosphors, giving values of recovery in the ranges of 96.5%-104%, 98.5%-105% for Pb, Hg in WFP, and 98%-104.5%, 98%-104.5% for Pb, Cd in WCP respectively, and values of RSD less than 8%. Also, influences by dilution factor, coexisting elements and HNO3 Concentration etc. were discussed in the paper.
