Adsorption of Cationic Dye Using A newly Synthesized CaNiFe 2 O 4 /Chitosan Magnetic Nanocomposite: Kinetic and Isotherm Studies

摘要: Chitosan biopolymer was extracted from chitin and utilized for the synthesis of CaNiFe2O4/Chitosan as a new magnetic nanocomposite. The structural morphological properties synthesized samples were characterized by FT-IR, XRD, XPS, SEM, TEM techniques. Adsorption methylene blue (MB) evaluated onto nanomaterial. UV–Vis spectrophotometry used to monitor removal efficiency. Batch experiments performed research effect various factors including solution pH, adsorbent dosage, contact time, MB initial concentration, temperature on adsorption MB. This study reveals that nanocomposite is indeed an effective, applicable, affordable with efficiency about 88 percent. highest recorded at 25 °C, 7.6 100 mg dosage. data validity estimated applying equilibrium models fitted linear non-linear regression (kinetic isotherm models). Thermodynamically, demonstrated spontaneity viability based (negative) values ∆G ∆H.
