Separation and recovery of heavy metals in chloride complexing solutions based on principles of electrochemical engineering

Christos Comninellis

This paper describes the selective recovery of heavy metals from a chloride contg. soln. The goal is to recover each heavy metal with high purity and yield by electrodeposition. The soln. contains four different heavy metals (Zn, Pb, Cu and Cd), high amts. ...

Electrochemical production of ceric sulfate in concentrated sulfuric acid

Christos Comninellis

The electrochem. prepn. of ceric sulfate [13590-82-4] was studied in concd. H2SO4 (10 mol/dm3). The current efficiency of the reaction increases considerably if a mixed catalyst (Ag2SO4 + MnSO4) is used. [on SciFinder (R)] ...

Electrochemical production of manganic sulfate in concentrated sulfuric acid

Christos Comninellis

The electrochem. prepn. of Mn2(SO4)3 [13444-72-9] was studied in concd. H2SO4 (15-17M). The reaction must be effected at high temp. (80-90 Deg) and in the presence of Ag ion as catalyst. [on SciFinder (R)] ...

The electrochemical production of cobaltic sulfate

Christos Comninellis

In the electrochem. prepn. of cobaltic sulfate the reaction is best done in 40 wt % H2SO4 in the presence of Ag ions as the catalyst, using PbO2 as the anode, with a low c.d. and a low conversion. [on SciFinder (R)] ...
