INVESTIGATION OF ELECTROCHEMICAL-BEHAVIOR OF ARS ON GC ELECTRODE BY SPECTROELECTROCHEMISTRY WITH LOPTLC

The electrochemical behavior of Alizarin Red S(ARS) on GC electrode has been studied in acidic condition by spectroelectrochemistry with LOPTLC. It was found that there are three electrochemical reactions and followed by a chemical reaction of ARS in the potential range of 1.00——0.60V. The mechanism of electrode reactions has been studied and suggested based on the informations obtained from electrochemical and insitu spectroelectrochemical experiments.

A NEW KIND OF FLOW-THROUGH ELECTROCHEMICAL DETECTOR USING CARBON-FIBER ELECTRODE FOR LIQUID-CHROMATOGRAPHY

An electrochemical detector which was constracted by using a carbon fibre electrode in a flow-through cell was connected with a liquid chromatographic column. Thus a sensitive,

ELECTROCHEMICAL TRANSFER OF 12-SILICOTUNGSTATE ANION ACROSS THE WATER NITROBENZENE INTERFACE

It has been firstly found by means of cyclic voltammetry (CV) and chronopotentiometry with linear current-scanning (CLC)that 12-silicotungstate anion (SiW_(12)O_(40)~(4-)) with high charge numbers, large molecular volume and symmetric structure can cross

SYNTHESIS AND CRYSTAL-STRUCTURES OF THE BIMETALLIC RARE-EARTH COMPLEXES AND STUDIES ON INSERTION MECHANISM OF DIENES POLYMERIZATION

The deepening of the studies on essentials of rare earth coordination catalyst brings about more and more reports on model compounds as active centre of the catalyst. Among them the most significant researches are those with identification of the crystal structures of compounds.

THIN-LAYER ELECTROCHEMICAL DETECTOR COATED WITH NAFION FILM

Electrochemical detection of the flow system has attracted considerable interest in recent years due to its high sensitivity and selectivity towards electroactive compounds. However, the improvement of sensitivity and selectivity is still a desire for practical application. In this note, a thin-layer electrochemical detector of the
