Removal of mercury@ and other heavy metals - from soil or slurries in electrolysis cell by suspending in electrolyte-contg. soln.

摘要

Removal of Hg and other heavy metals from soil and slurries comprises placing the soil-slurry into an electrolysis cell by suspending in an electrolyte-contg. soln. and stirring the suspension. The dispersed soil-slurry is moved towards the electrodes, where non-ionogenic heavy metals, esp. Hg, are initially oxidised at the anode and subsequently deposited at the cathode. ADVANTAGE - Hg and other heavy metals can be quickly and effectively removed
