Wiedza o strukturze porowatej węgli aktywnych, w tym o ultramikroporach, mikroporach i mezoporach, ma zasadnicze znaczenie w zastosowaniu tych materiałów do różnych celów. Zazwyczaj charakterystyka tych materiałów obejmuje wyznaczenie powierzchni właściwej, objętości porów i funkcji rozkładu objętości porów. Tę ostatnią funkcję wyznacza się na podstawie doświadczalnej izotermy adsorpcji azotu w temperaturze...
Adsorption isotherms of water vapor measured on unmodified and strongly oxidized active carbons at 298 K were analyzed by using different isotherm equations. It was shown that the wellknown Dubinin-Serpinsky equations fail to describe adsorption isotherms of water vapor on strongly oxidized active carbons. However these isotherms can be well described by equations of the theory of the micropore volume...
