Folic acid is soluble in 0,1 M NaOH and Chitosan-g-folic acid is soluble in acetic acid. If I try to prepare the calibration curve, what solvent I have to use?
your material is soluble in polar solvent,therefore you must use a non-polar solvent like chloroform,CCl4 or n-hexan for preparing calibration curve
Thank you!
