Aminopyrene functionalized mesoporous silica for the selective determination of resorcinol
چکیده انگلیسی

Aminopyrene was convalently anchored onto the surface of mesoporous MCM-41 silica by post-grafting. This organic–inorganic hybrid has been applied as sensing material to phenols determination. Experimental results reveal that the functionalized material presents good sensitivity and selectivity towards resorcinol and can be used for resorcinol determination in water at pH 6.0. The fluorescence intensity of aminopyrene functionalized mesoporous silica decreases proportionally to the logarithm of resorcinol concentration in water. The linear range for resorcinol detection lies in 4.79–163 μM with a detection limit of 2.86 μM (S/N = 3).
