in this paper, the effect of penicillin g drug as a green corrosion inhibitor on mild steel in 1.0 mhydrochloric acid solution has been investigated using potentiodynamic polarization, electrochemicalimpedance spectroscopy (eis) and electrochemical noise (en) techniques. the inhibition efficiencywas found to increase with increasing inhibitor concentration. potentiodynamic polarizationmeasureme...

In this work, a synthetic textile effluent containing a reactive dye (C.I. Reactive Orange 4) was treated in an electrochemical cell with titanium covered by platinum oxide (Ti/PtOx) electrodes to remove color. The discolored effluent was mixed with other textile mill process effluents (scouring, bleaching, washing, etc.), according to the rate of each effluent in the mill, and was submitted to...

A surplus of glycerol production due to several reasons has initiated investigation of several routes of oxidative glycerol upgrading. Among the reaction products are substances such as dihydroxyacetone and several acids from oxidative upgrading of glycerol. Several routes of chemical oxidation and electrochemical oxidation have been published in literature. The ongoing project has focused on t...

Electrochemical sensors have the capacity for rapid and accurate detection of a wide variety of target molecules in biological fluids. We have developed an electrochemical sensor assay involving hybridization of bacterial 16S rRNA to fluorescein-modified detector probes and to biotin-modified capture probes anchored to the sensor surface. Signal is generated by an oxidation-reduction current pr...

Background: Electro-oxidation is developed as an electrochemical method to overcome the problems of  the conventional  decolorization technologies and is an appropriate alternative for the treatment of colored wastewater from various industries. The purpose of this study was to evaluate the efficiency of the electrochemical oxidation process in  removal  of chemical oxygen demand (COD) and Acid...

1. Theoretical considerations lead to the conclusion that dissociable acidic groups present to a varying extent in different collodion preparations determine the electrochemical behavior of membranes cast from these preparations. It is further reasoned that the base exchange capacity of the collodion surfaces is the true quantitative measure of the abundance of the dissociable groups. 2. The co...

This work compares structural and optical properties of silicon nanocrystals prepared by two fundamentally different methods, namely, electrochemical etching of Si wafers and low-pressure plasma synthesis, completed with a mechano-photo-chemical treatment. This treatment leads to surface passivation of the nanoparticles by methyl groups. Plasma synthesis unlike electrochemical etching allows se...

In recent years, combinatorial methods have attracted a great deal of attention. Among them, sono-combining techniques have shown a significant potential as an economic technology applicable and environment-friendly technology for wastewater treatment. In this study, Sono Electrochemical SE, Sono Photo Electrochemical SPE and Sono Photo Electro Catalytic SPEC techniques were investigated for de...
