Daftar Isi:
- Preparation of the c hitosan membrane of ion-selective electrode for determination of cadmium ion has been conducted. Chitosan is a natural polymer containing nitrogen could coordinate with CcP to increase the membrane conductivity v alue. Chitosan is a principal material and mixed with polyvinylchloride (PVC) as matrix dissolved previously to solvent tetrahydrofuran (THF) and dioctylphenylphosphonate (DOPP) is added as plasticizer by proportion chitosan: PVC: DOPP (6:3:1). To obtain the dopant optimum concentration, membrane was dipped in Cd2⁺
