Mechanistic analysis of the cathodic stripping square-wave voltammetric response of the copper‑arsenic system at a mercury electrode
(Elsevier Science SA, 2020-11-11)
Despite arsenite can be reduced to As(0) and deposited at the surface of solid electrodes such as gold, platinum, or copper, it cannot form amalgams with mercury, and so the addition of other metal ions is required for its ...
REMOVAL OF ARSENIC FROM ENARGITE RICH COPPER CONCENTRATES
(JOHN WILEY & SONS INC, 2013)
Arsenic is a troublesome impurity in copper concentrates where it is usually present as enargite (CU3AsS4). When the enargite content is high in the concentrates, they cannot be treated by direct smelting processes because ...
Arsenic speciation in water samples containing high levels of copper: removal of copper interference affecting arsine generation by continuous flow solid phase chelation
(SPRINGER HEIDELBERG, 2005-04)
A simple continuous flow method is proposed to eliminate copper interference in arsenic speciation by hydride generation, based on the selective retention of this interfering ion in an iminodiacetate chelating resin previous ...
