Can curcumin acquire a positive charge, below pH 7?

05 May 2018 1 3K Report

Why is it that when you do a PZC study of curcumin between pH 4 and pH 8 the surface is negative throughout. Can someone please explain, I'm trying to find out if curcumin can acquire a positive charge below pH 7.

Dear Luthando Tshwenya

I would suggest you should take a wide range for pHzpc study. may be at highly acidic conditions or highly basic conditions only it would get positive charge.
