Abstract
An apparatus and a method for the rapid determination of specific surface areas are described. The method is based on low temperature adsorption of nitrogen from the air and requires determination of the adsorbed gas at two relative pressures. The accuracy of the method, as compared with the BET technique, is ±9% for the adsorbents studied.
Abstract
Были предложены метод и аппаратура для быстрого определения удельной поверхности. Метод основан на низкотемпературной адсорбции азота из воздуха и требует определения адсорбированного газа при двух относительных давлениях. Точность метода, по сравнению с техникой BET, составляет ±9% для изученных адсорбентов.
