Mesoporous Silica: A Suitable Adsorbent for Amines

By Cyrus Zamani, Xavi Illa, Sara Abdollahzadeh-Ghom, JR Morante and Albert Romano Rodríguez

Abstract

Mesoporous silica with KIT-6 structure was investigated as a preconcentrating material in chromatographic systems for ammonia and trimethylamine. Its adsorption capacity was compared to that of existing commercial materials, showing its increased adsorption power. In addition, KIT-6 mesoporous silica efficiently adsorbs both gases, while none of the employed commercial adsorbents did. This means that KIT-6 Mesoporous silica may be a good choice for integrated chromatography/gas sensing micro-devices
