A Batch-Wise Flow Analyzer for the Determination of Chloride in Potable Waters Using Differential Electrolytic Potentiometry

Multiwalled Carbon Nanotubes-Modified Metallic Electrode Prepared Using Chemical Vapor Deposition as Sequential Injection Analysis Detector for Determination of Ascorbic Acid

“…Differential electrolytic potentiometry (DEP) has been used as an indicating system for the quantitation of ascorbic acid in pharmaceutical and food samples using conventional titrations [ 37 , 38 ], and in SIA systems [ 39 , 40 ]. SW polarized working electrodes exhibited more sensitivity and lower detection limit due to the great acceleration of the electrode response and significant decrease in the electrode deactivation [ 41 ].…”

Inhibition of Corrosion of Carbon Steel in Sea Water by Sodium Gluconate - Zn2+ System

“…Thermodynamic studies [19], quantum chemical studies [35], and electrochemical studies [4] have been employed to explain the inhibitive actions of carboxylic acids. Phosphono carboxylic acids [29,31,32], tartrates [8,10], amino acids [19] and citrates [1] have been used as corrosion inhibitors. The present work is undertaken (i) to evaluate the inhibition efficiencies of sodium gluconate (SG)-Zn 2+ system in controlling corrosion of carbon steel in sea water by weight-loss method, (ii) to investigate the mechanistic aspects of corrosion inhibition by electrochemical studies like polarization study and AC impedance spectra, (iii) to analyse the protective film by FTIR and luminescence spectra, (iv) to analyse the surface morphology by AFM, and (v) to propose a suitable mechanism of corrosion inhibition based on the results from the above study.…”
