摘要: Abstract A method is proposed for determination of surface compounds containing nitrogen incorporated into activated carbon and other adsorbents. The based on the redox reaction between hydrochloric acid compounds. Materials obtained by treating with concentrated nitric or hydrogen peroxide as well passing oxide through thermal treatment samples pretreated were investigated. It was established that which proceeds only in presence groups both oxygen. I.r. spectroscopy XPS showed organic nitrates nitrate complexes NO 3 − can be determined method.
