“…In studies carried out by Elsherief [18] on the removal of Cd(II) using a spiral wound steel electrode, similar concentration decay curves were obtained. When 250 lA cm )2 was applied to the electrode, an exponential concentration decay was not observed, but it was for 400 lA cm )2 .…”

“…Barbosa et al [17] used a mild steel wool and a stainless-steel mesh coil for gold electrowinning and they found that electrolyte recirculation enhanced the gold recovery from the diluted liquors. Elsherief [18] developed a flow-by cell with a spiral wound steel electrode for Cd(II) electrowinning. For a 250-ml solution volume and optimized operating conditions, the Cd(II) concentration was decreased from 500 ppm to less than 5 ppm in 90 min.…”

The investigation of an electrolytic process to remove Pb(II) from simulated wastewaters using a stainless-steel wool (SSW) cathode in a flow-through cell under potentiostatic condition is reported. Voltammetry under hydrodynamic conditions was used to estimate the diffusion coefficient, which was found to be 1.4 Â 10 )5 cm 2 s )1 in the supporting electrolyte (0.10 mol l )1 NaNO 3 and 0.10 mol l )1 H 3 BO 3 , pH 4.8). The performance of the flow-through cell was evaluated for three potentials: )0.70, )0.80 and )0.90 V vs. saturated calomel electrode (SCE). At )0.70 V, the reaction was found not to be completely controlled by mass transfer, while at )0.80 V and )0.90 V the Pb(II) concentration decayed exponentially. At )0.90 V, using a flow rate of 250 l h )1 , after a 90-min electrolysis, the Pb(II) concentration decayed from 50 ppm to only 1 ppm, corresponding to a 98% removal.

Cd-Pb thin films were electrodeposited from a diluted chloride solution using stainless steel rotating disc electrode. The linear sweep voltammograms of the single metallic ions show that electrodeposition of these ions was mass transfer control due to the plateau observed for different rotations at concentration (50 and 200 ppm). The voltammograms of binary system elucidate that electrodeposition process always start at cathodic potential located between the potential of individual metals. Currents transients measurements, anodic linear sweep voltammetry (ALSV) and atomic force microscopy (AFM) were used to characterize the electrocryatalization process and morphology of thin films. ALSV profiles show a differentiation for the dissolution process of individual metals and binary system. Two peaks of dissolution Cd-Pb film were observed for the binary system with different metal ion concentration ratios. The model of Scharifker and Hills was used to analyze the current transients and it revealed that Cd-Pb electrocrystalization processes at low concentration is governed by threedimensional progressive nucleation controlled by diffusion, while at higher concentration starts as a progressive nucleation then switch to instantaneous nucleation process. AFM images reveal that Cd-Pb film electrodeposited at low concentration is more roughness than Cd-Pb film electrodeposited at high concentrated solution.

“…Several treatment processes have been suggested for the removal of cadmium from aqueous waste streams, such as adsorption on activated charcoal [1], biosorption on marine algae [2], ion exchange [3], cathodic reduction [4,5], chemical precipitation [6], electrodialysis [7], and electrodeionization [8][9][10][11].…”

In this study, electrostatic shielding zones made of electrode graphite powder were constructed and used as a new type of ionic and electronic current sinks. Because of the local elimination of the applied electric field, voltage, and current within these zones, ions are led inside them and accumulate there. The current sinks were implemented in electrodeionization of simulated cadmium plating rinse waters containing 50 mg/L of Cd 21 ions with simultaneous electrochemical regeneration of the ion exchange resin beds. Pure water was obtained with a Cd 21 ion concentration of less than 0.1 mg/L at a flow rate of 3.27 3 10 24 L/s diluate stream, a current density of 2 mA/ cm 2 , and a current efficiency of 28% for Cd 21 ion removal.
