Аннотация
Modified flocculation magnesium silicate is prepared by a hydrothermal process at 120°C for 18 h after adding Al2(SO4)3 into the magnesium silicate gel. Compared with standard magnesium silicate with 328.116 m2 g–1 surface area, this modified magnesium silicate has a bigger BET surface area of 536.803 m2 g–1 and a lower interlayer water content. Modified magnesium silicate exhibits high β-carotene adsorption with a maximum adsorption capacity of 364.96 mg g–1. It is shown that when suspended in organic solvent, this material can be used effectively for carotenoid separation. Furthermore, our results suggest that modified magnesium silicate may be a promising candidate as an absorbent in the decoloring of oil.
