Experimental design investigation for vermiculite modification: Intercalation reaction and application for dye removal
Source abstract
Abstract
With the aim to improve the anionic dye sorption capacity of vermiculite, ethylenediamine was employed to modify vermiculite under different conditions. In this study, a 24 factorial design was used for organovermiculite preparation to assess the influence of the temperature (303 and 323 K), ethylenediamine concentration (0.1 and 0.2 mol L− 1), reaction time (24 and 48 h) and acid activation of the clay mineral (leached and non-leached samples). The pristine and modified solids were characterized by CHN elemental analysis, infrared spectroscopy and X-ray diffraction. Principal component analysis and hierarchical cluster analysis were performed on the IR spectra to investigate the effect of parameter variation on the vermiculite modification. The reaction temperature and the acid activation of the vermiculite significantly influenced the vermiculite structural features. The optimized sample presented good adsorption capacity for Remazol Brilliant Blue RN, 11.02 mg g− 1. This study concluded that vermiculite modified with ethylenediamine behaved as a good sorbent to anionic dye.
