A new process to pretreat blood samples has been developed. This process combines the Advanced Oxidation Process (AOP) treatment (using H(2)O(2) and UV irradiation) with acid deactivation of the enzyme catalase in blood. A four-cell reactor has been designed and built in house. The effect of pH on the AOP process has been investigated. The kinetics of the pretreatment process shows that at high...

in this investigation, attempts were directed to study the inhibitive effects of nitrite and phosphate base inhibitors for the carbon steel alloy samples, which are used in an acid gas treatment process (the sulfiran® solution), in fe-edta solution. electrochemical techniques, i.e. polarization curves and electrochemical impedance spectroscopy (eis), were used to evaluate the inhibition efficie...

The main objective of this study is removal of pathogenic bacteria using electrochemical process. The bactericidal effects of electrochemical system containing steel mesh electrode were evaluated from contaminated water with E. coli, Pseudomonas aeroginosa, Staphylococcus aureous and Streptococcus fecalis at various concentrations. Effect of current density, supporting electrolyte and pathogeni...

in the present study, five modeling approaches of ra, mlp, mnn, gff, and canfis were applied so as to estimate the radial overcut values in electrochemical drilling process. for these models, four input variables, namely electrolyte concentration, voltage, initial machining gap, and tool feed rate, were selected. the developed models were evaluated in terms of their prediction capability with m...

Electrochemical capacitors, also called supercapacitors, store energy using either ion adsorption (electrochemical double layer capacitors) or fast surface redox reactions (pseudo-capacitors). They can complement or replace batteries in electrical energy storage and harvesting applications, when high power delivery or uptake is needed. A notable improvement in performance has been achieved thro...

*Corresponding author Email: [email protected] In this work, the treatment of organics present in printing ink wastewaters such as dyes (methylene blue and rhodamine B), surfactants (sodium dodecylbenzene sulfonate), and solvents (ethylene glycol), as well as actual printing ink wastewaters by advanced oxidation processes, namely conductive diamond electrochemical oxidation (CDEO), Fenton...

This paper presents a model-based approach on the analysis of complex multidisciplinary electrochemical processes, with implementation on a reactor for the electrochemical conversion of CO2 to formate/formic acid. The process is regarded as a system of interacting physical and electrochemical mechanisms. A process model is developed by combining individual mathematical sub-models of the mechani...

background: high concentration of salt makes biological treatment impossible due to bacterial plasmolysis. the present research studies the process of electrochemical oxidation efficiency and optimal levels as important factors affecting ph, salt concentration, reaction time and applied voltage. methods: the sample included graphite electrodes with specifications of 2.5 cm diameter and 15 cm he...
