One investigated way to prepare selective adsorbents towards mixtures of volatile organic compounds (VOCs) is to modify lignite by nitrogen-enrichment. These chemically modified coals are prepared by condensation of urea with the lignite before the c

The aim of this work is to study the efficiency of the nitrogen enrichment by urea of lignites and the induced changes of the adsorptive properties towards volatile organic compounds (VOCs) of the activated carbons derived from these modified precurs

The effect of CF 4 -plasma enhanced fluorination on the surface modification of carbon blacks has been examined using XPS. Three different types of carbon blacks have been studied: a thermal black, a furnace black and a high electrical conducting bla

The fluorination of a furnace carbon black (N115 from Degussa) with gaseous F2, diluted in N2, at room temperature was studied by XPS. The influence of the reaction parameters (% of F2 in the gaseous mixture, duration of contact) and activation (O2 a

Irreversible fixation of poly(methylmethacrylate) (PMMA) on the surface of non-porous alumina was examined by FTIR, XPS and NMR spectroscopies. The hydrolysis of side ester groups of PMMA is evidenced: PMMA bonds strongly to the alumina surface throu
