Copper Sensor System for Unattended Marine Operations III: Detecting Copper(I) in the Marine Environment with Fiber Optic Technology

Abstract

Since the ionic forms of copper(I) and copper(II) arc toxic in the marine environments, a portable and easy-to-use rapid-measurement sensor capable of measuring parts per billion (ppb) levels of ionic copper COPPER(I) and copper(II) in the marine environment is needed. This study tests the hypothesis that the organic reagent bathocuproine (BCP) can be immobilized to develop a fiber optic sensor capable of measuring copper(I) in seawater. This work describes the response of a first-generation fiber optic/copper(I) probe. Results indicate that the fiber optic probe has sensitivity in the ppb range with a lower detection limit of 17 ppb. In addition, reduction of copper(II) to copper(I) using hydroxylamine hydrochloride allows the fiber optic probe to determine total ionic copper.
