Preparation of Magnetic Nano Composite Modified with Orange Peel for Adsorption of Vitamin B5 from Aqueous Solution

One of the most important vitamins for human life is pantothenic acid (B5), because of its advantages such as production of blood cells, adrenal gland activity, stress management and energy production. The presence of this vitamin is important for plant growth and food production, because of its adsorption and determination were studied more than before.  Magnetic Nano adsorbent has been attracted great attention in the field of separation due to the simplicity, low cost and high speed. In this paper, the magnetic Nano composite modified with orange peel for adsorption efficiency of vitamin B5 from aqueous solution was synthesized. The Nano adsorbent structure was characterized using SEM-EDX, FTIR and XRD. The influence of adsorption parameters including pH, contact time, adsorbent dosage and initial concentration of B5 onto Nano adsorbent were evaluated. The best sorption of B5 via the Nano sorbent occurred at concentration of 300 mg L-1, 0.1 g of Nano adsorbent, 90 min of contact time at an optimum pH of 6. The Langmuir isotherm model (R2= 0.9899) was found to be fit with the isotherms data. The best kinetic model fit for adsorption of B5 from Nano adsorbent was found with the pseudo-first-order model (R2=0.9999).
