Removal of rhodamine B from aqueous solutions using vanadium pentoxide/titanium butyl oxide hybrid xerogels

A stable and insoluble V₂O₅·nH₂O/tetra-n-butyl titanate (TBO) hybrid xerogel was synthesized by the sol-gel method. This novel material proved to be an efficient absorbent with an absorption capacity of 179 mg·g^-1 for Rhodamine B (RhB) in water due to its unique layered structure, which can effectively accommodate RhB molecules between its layers as demonstrated by XRD and FTIR spectroscopic analyses.
