a-Nitroso-B-Naphtol Encapsulation for Retention of Cu(II) Metal Ion
In this research, microcapsule material has been developed by encapsulating a-Nitroso-B-Naftol inside Ca-alginate. This microcapsule is expected to have a metal ion Cu2+ retention property through the making of a-Nitroso-B-Naftol complex. Various considerations that influence both the capsule making...
