Spectrofluorimetric determination of surface-bound thiol groups and its application to the analysis of thiol-modified silicas

A sensitive spectofluorimetric method has been developed for the quantitative measurement of surface-bound thiol groups. The procedure is based on the quantitative esterification of the thiol group with Rhodamine B and its subsequent release from the solid by base hydrolysis for spectrofluorimetric...
