Adsorption of nitrophenol onto a novel Fe₃O₄-κ-carrageenan/MIL-125(Ti) composite: process optimization, isotherms, kinetics, and mechanism.

ABSTRACT: Water pollution is a dreadful affair that has incessantly aggravated, exposing our planet to danger. In particular, the persistent nitro aromatic compound like nitrophenols causes anxiety to the researchers due to their hazardous impacts, excessive usage, and removal difficulty. For this purpose, a novel multi-featured composite was constructed based on κ-Carrageenan (κ-Carr), MOF (MIL-125(Ti)), and magnetic Fe₃O₄ for efficient adsorptive removal of o-nitrophenol (o-NP). Interestingly, BET measurements revealed the high surface area of Fe₃O₄-κ-Carr/MIL-125(Ti) of about 163.27 m²/g, while VSM showed its excellent magnetic property (20.34 emu/g). The comparison study pointed out the synergistic effect between Fe₃O₄,
