3.2.1 Investigating effect of magnetic metal-organic framework
nanocomposite dose on curcumin uptake
To investigate the effect of the interaction of curcumin molecules with
magnetic metal-organic framework nanocomposite, prepared the aqueous
solution of curcumin with a concentration (100 mg /L) and then 100 ml of
solution were sampled. Calculate the amount of curcumin in solution and
added to various ratios of (1:2), (2:1) and (1:1) magnetic metal-organic
framework nanocomposites
(NiFe2O4@SiO2@HKUST-1)
with weight percentage (30% wt.). Placed the solution on the shaker for
better mixing. Sampling and centrifugation performed every 2 hours and
spectrophotometer used to measure the wavelength and the absorption
value was calculated.
Fig(5). Investigation of the effect of nanocomposite concentration on
curcumin
Fig (5) showed, as the nanocomposite ratio of the magnetic metal-organic
framework to curcumin increases, the adsorption efficiency increases. It
was also obtained that the maximum efficiency (90%) were riched after 8
hours when the nanocomposite of the magnetic metal-organic framework of
the magnet was double of the amount of curcumin used in the solution.
This increase in efficiency is due to the increase in sites and free
puros due to the increase in the concentration of metal-organic
framework nanocomposite compared to the concentration of curcumin in the
solution.
