Abstract
A new method for the quantitative determination of zeolitic Bronsted a cidity is proposed utilizing the specific low-temperature reaction of NH4+ ions fixed to Bronsted sites with NO-O-2 thus preventing the loss of acid sites normally encountered for the conventional temperature-p rogrammed mode of NH3 thermodesorption.
