Electrogravimetry

INTRODUCTION

Luckow first discovered the electrogravimetry for the determination of the copper. Then Alexander Classen first published the paper on the electrogravimetry in 1881. After that, Gibb's was the first founder of the electrogravimetry for the deposition of the metals on the mercury cathode. Electrogravimetry is a method for the separation of the metal ions by using the electrodes. The deposition takes place on the one electrode.
