Two chitosan silica hybrid materials were prepared by a two-step process in 78–84% yields using the homogeneous phase reaction of 3-(triethoxysilyl)propyl isocyanate with chitosan dissolved in 1-n-butyl-3-methylimidazolium chloride ionic liquid (∼10% w/w), which was followed by NH4OH catalyzed hydrolysis of triethoxysilyl groups and then sol-gel process. These new hybrid materials were shown to adsorb up to about 95% of Fe3+ from 5 × 10−4 M aqueous solution at room temperature in 24 h.

Dyes are intensively used in industries such as textiles, plastics, cosmetics, etc., and they are considered major wastes. Due to their chemical structures, dyes are resistant on exposure to sun or water, therefore being difficult to be removed once released into the aquatic environment, having serious environmental impact. Among these dyes, rhodamine is a fluorescent dye. The mesoporous SBA-16 nanosilica has been synthesized by sol−gel process. The rhodamine 110 adsorption process on SBA-16 was explained by Langmuir and Henry isotherm models. The excellent adsorption and fluorescence properties reduction indicated that the mesoporous silica can be efficiently applied in the wastewater treatment.
