Bisphenol A (BPA) is a compound known as one of the main endocrine disruptors present in the environment. The consequences of this presence have been widely reported in recent years and several health effects have been attributed to the presence of BPA in the human body, such as many kinds of cancer, decreased sperm count and fertility, among others. This compound is widely used in the chemical...

The purpose of this study is mainly to evaluate the performance of the continuous recirculation flow cell at low current density and pH (the pH at which the effluents are available) in removing heavy metals from copper smelting effluent by cathodic reduction. During the electrolysis at different pH, % removal of heavy metals removal, energy consumption and heterogeneous reaction rate constants ...

A water treatment technology employing the adsorption of dissolved organic contaminants from water and their electrochemical regeneration has been commercialized by Arvia Technology Ltd, UK. This technology focuses the adsorption of pollutants onto the surface of low surface area graphite based adsorbents followed by the anodic oxidation of adsorbed species in an electrochemical cell. However, ...

We discussed here on a novel approach to recycle CO2 back to liquid fuels by using nanostructured carbon-based materials (doped with suitable metal nanoparticles) as electrocatalysts. This approach is based on the development of a new photo-electrocatalytic (PEC) reactor, working in gas phase, which is quite different from the conventional reactors that operate typically in aqueous slurry and/o...

A finite-difference method for predicting the current-density distribution in multi-ion electrolytes was developed, then implemented to actual experimental systems and compared with other numerical methods, analytic solutions for limiting conditions, and experimental measurements in order to be tested. The method accounted for diffusion, ionic migration, laminar convection, and heterogeneous el...

We present an electrochemical advanced oxidation process (eAOP) reactor employing expanded graphite, potassium iodide (KI), and electrical current, which demonstrates exceptionally high rate of inactivation Escherichia coli (106 or 6 log10 reduction in viable cells) at a low current density (0.12 mA/cm2), with short contact time (5 min) concentration KI (10 ppm, 0.06 mM). Advanced spectroscopic...

It has been found that polyoxometalates (POMs) can act as mediators in the electrochemical oxidation of lignin in pulps. An electrochemical cell, with a Nafion membrane separating the anode and cathode compartments, was used in the delignification experiments. A softwood kraft pulp was placed in the anode compartment with a buffered 0.01M solution of the polyoxometalate Na5[SiVW11O40]. During e...

This work focuses on the importance of choosing a suitable electrochemical cell to remove antibiotics from urines. For this purpose, we investigate use two cells for electrolysis and photo-electrolysis urine polluted with mixture Penicillin G, Meropenem, Chloramphenicol. The reactors studied were conventional flow pass (E-cell) microfluidic flow-through reactor (MF-Reactor). Both are equipped m...

The focus on renewable energy is increasing globally to lessen reliance conventional sources and fossil fuels. For systems work at their best produce the desired results, precise feedback control required. Microbial electrochemical cells (MEC) are a relatively new technology for energy. In this study, we design implement model-based robust controller continuous MEC reactor. We compare its perfo...
