摘要:

研究了以多种方法化学改性的不同活性炭表面化学特性及十二硅钨酸(SiW_(12))在相应表面的吸附. 首次提出,不同原料来源和改性的活性炭对SiW_(12)的吸附有不同的等温线形式和吸附力. 活性炭表面的羰基有利于SiW_(12)的吸附,而表面的羧基则是不利的.

关键词: 活性炭, 吸附, 杂多酸, 固载化

Abstract:

The surface chemincal species of surface-modified activated carbons and ad sorption of 12-silicotungstic acid (SiW_(12)) on them were studied It was found that these carbons have different adsorption isotherms and adsorptive force. The carbonyl groups on the surface of activated carbon were favorable while carboxyl groups were unfavourable for the adsorption of SiW_(12).

Key words: Activated carbon, Adsorption, Heteropolyacids, Heterogenization
