A group of modern wool and cotton samples prepared as mordanted standards was subjected to particle-induced x-ray emission analysis (PIXE). The mordants applied were potassium aluminum sulfate, cupric sulfate, ferrous sulfate, stannous chloride, and potassium dichromate. Results agreed with analyses of identical mordanted standards by energy-dispersive x-ray spectrometry in a scanning electron microscope (SEM-EDS).
