If I had to use higher concentration of acetic acid to dissolve chitosan, would it be difficult to reduce Cu ions when copper sulphate solution is added? Do I need to increase the pH a bit?
I have to analyse my Chitosan Cu nanocomposite sample through XPS. I need an idea about the energy of Ar+ ion and the time of sputtering if etching is done prior to XPS analysis.
