Synthesis, Spectroscopic, and Antibacterial Characterizations of Cadmium-Based Nanoparticles.

In the current study, the co-precipitation technique was employed for the synthesis of Cadmium oxide (CdO) and Copper‒doped Cadmium oxide (Cu‒CdO) nanoparticles. The synthesized samples were subjected to powder X-Ray diffraction (P-XRD), Field emission scanning electron microscopy (FE-SEM), Energy-dispersive X-ray (EDX), Fourier transforms Infrared (FT-IR), UV-Vis spectroscopy, photoluminescence (PL), laser-induced fluorescence spectroscopy and antibacterial investigations. According to the P-XRD analysis, both the samples were simple cubic in structure and have average grain sizes of 54 and 28 nm, respectively.

Electrolytic recovery of dilute copper from a mixed industrial effluent of high strength COD.

In this study, the electrochemical treatment has been investigated in the real acidic effluent of copper-phthalocyanine dye manufacturing plant. Galvanostatic batch electrolyses have been carried out in an undivided cell using stainless steel as cathode, dimensionally stable anode (DSA) and graphite as anodes at different current densities and temperatures. The influence of these variables on current efficiency, cell voltage, energy consumption and deposit quality was reported.

Evaluation of electrochemical oxidation techniques for degradation of dye effluents--a comparative approach.

The high energy cost of an electrochemical method is the fatal drawback that hinders its large scale application in wastewater treatment. The traditional single-chamber electrochemical method used in the waste water treatment mainly focused on anodic oxidation, but hydrogen produced on the cathode and indirect electrochemical treatment involves application of an electrical current to the wastewater containing chloride to convert into chlorine/hypochlorite. The two-compartment electrolytic cell, separated by an anion exchange membrane, has been developed in this work.
