Abstract

Abstract: Self-assembled monolayers(SAMs) of mercapto methoxy poly(ethylene glycol)(MPEG) on gold electrode surface was formed. The SAMs of MPEG had molecular recognition characteristics. The iodine ions could permeate through the SAMlayer to approach the electrode surface. This MPEG film electrode can be used to detect iodine ions with lower interference.

Key words: Mercapto methoxy poly(ethylene glycol), Self-assembled monolayers, Iodine ions, Electrochemistry analysis
