Abstract
A rapid infrared determination of the amount of gypsum present in marble by infrared spectroscopy on a solid sample has been developed. A very small sample, about 1 mg is mixed with potassium bromide and made into a disc according to the usual technique. The absorbances at 877 cm-1 and 602 cm-1 which are proportional to the concentrations of gypsum and marble are measured. The accuracy of the method within a 6-94% concentration of gypsum is 3%.
