Actually chitosan can be dissolved in acidic solutions. And in general chitosan based sorbents when functionalized with cross-linking agents improves the acid stability.
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...
