Barium and Selenium in Pigment-Printed Textiles
topic
Barium and selenium determination in pigment-printed textile specimens uses microwave acid digestion followed by ICP-MS analysis, targeting barium sulfate extender pigments and selenium-based cadmium sulfoselenide red and orange pigments historically used in textile screen printing and now restricted under multiple international chemical safety frameworks.
Role
Ensures pigment-printed textiles and transfer-printed fabrics do not contain barium or selenium compounds at concentrations exceeding toy safety and consumer textile limits, addressing the replacement of cadmium-containing coloured pigments in the textile printing industry with safer high-performance organic alternatives.
