A method has been developed to determine 15 elements in leather samples by ultrasonic nebulization axial view inductively coupled plasma optical emission spectrometry (USN-ICP OES) after calibration by on-line internal standardization (IS). Samples were ground in a lab blender and decomposed following a simple digestion protocol with nitric acid and hydrogen peroxide under microwave heating. Owing to the high chromium content in samples, judicious selection of analytical wavelengths was… CONTINUE READING
