Abstract
A way is proposed for determining the quality of bleaching earths obtained by acid activation of bentonite using simultaneous thermal analysis. The qualitative characteristics of obtained adsorbent depend on the degree of structural preservation of the initial montmorillonite and the content of amorphous silica. The assessment of quality of modification using thermal curves can be applied for developing the regime and controlling the quality of acid activation of bentonites while obtaining an adsorbent with well developed specific surface.
