The GO-NH2-Fe3O4 was then evaluated as adsorbent of the cationic dye Methylene Blue (MB); analysis of the point of zero net charge (pHPZC) and pH effect showed that the GO-NH2-Fe3O4 pHPZC was 8.2; hence, the MB adsorption was …
WebApr 10, 2024 · Introduction. As a convenient liquid hydrogen (H 2) carrier with a high H 2 capacity (12.6 wt%), the “methanol-hydrogen” energy system has been suggested by George A. Olah in the conception of “methanol economy” [1], aiming at addressing the transportation and storage issues in H 2 application, thus promoting the large-scale … Amines can be classified according to the nature and number of substituents on nitrogen. Aliphatic amines contain only H and alkyl substituents. Aromatic amines have the nitrogen atom connected to an aromatic ring. Amines, alkyl and aryl alike, are organized into three subcategories (see table) based on the … See more In chemistry, amines are compounds and functional groups that contain a basic nitrogen atom with a lone pair.
