IR peaks of amberlite XAD-1180 resin
If you can give us the IUPAC name or chemical structure of these resins , that will be better to differentiate between them. I known they are a huge molecular weight.
I have performed the optimization of pH ranging from 2-9 so that I can choose one pH value for subsequent experiments but the results pertaining to pH values from 3-9 are almost near.How do I...
