A fluorescent X-ray method was proposed for the rapid determination of aluminum, chlorine, titanium and iron in high-density polyethylene.<BR>The calibration curves were drawn on synthetic standards prepared by mixing standard materials (aluminum oxide, sodium chloride, titanium oxide and ferric oxide) each corresponding to 5400 ppm of the inspected element into purified high-density polyethylene.<BR>The method is five to seven times more rapid than chemical procedures, and the accuracies were, Al: σ = 112% for 50400 ppm, Cl: σ =42% for 50400 ppm, Ti: σ =182% for 3100 ppm, and Fe: σ=242% for 1100 ppm.
