of 2 and temperature of 323 K. They proposed the following interaction
mechanism: H- bonds were formed between the VO-3R and lingocellulose
through water molecules, which were essential for the interaction. Kyzas
et al. [24] proposed the use of untreated coffee residues for the removal of
Remazol Blue RN (RB) and Basic Blue 3G (BB) from aqueous solutions.
