Preparation of organovermiculites using HDTMA: Structure and sorptive properties using naphthalene

Three types of organovermiculites with various organic cation (HDTMA) loading were prepared to be used as sorptive material for non-ionic organic compounds. The prepared materials were characterized using XRD and TOC analysis. The experiments evolved the fact that lower loading of HDTMA is more acceptable for sorption of neutral organic molecules from aqueous solutions. One of the possible models of intercalated molecules arrangement in vermiculite spacing was proposed.

Graphical abstractThree types of organovermiculites with various organic cations (HDTMA) loading were prepared to be used as sorptive material for non-ionic organic compounds. The experiments evolved the fact that lower loading of HDTMA (50% of CEC) is more acceptable for sorption of neutral organic molecules from aqueous solutions. One of the possible models of intercalated molecules arrangement in vermiculite spacing was proposed.Figure optionsDownload full-size imageDownload as PowerPoint slide
