Development of an Electrochemical Technique for the Removal of Ultratrace Levels of Heavy Metals from Water Using Accelerated Electrodeposition

A readily available source of ultrapure water is a basic requirement in most analytical work. The earliest requirement for ultrapure water was in electrochemical research^1. In recent years, nuclear reactors, semiconductor and electronic industries require very pure water^2,3. Ultrapure water is needed to prepare standards whenever the determination of ultratrace (ppb) concentrations of metals is required.
