“…This potential is related to the oxidation of monomers to radical cation, which is considered to be the first step in the polymerization of the conducting polymer. [33][34][35][36]38 The lower onset potential for the oxidation of pyrrole by comparison with 2-amino-4-phenylthiazole indicates that the oxidation of pyrrole is faster than that of 2-amino-4-phenylthiazole.…”

“…The kinetics of the chemical and electrochemical polymerization of some meta, ortho, and N-substituted aniline, thiazole derivatives, and pyrrole in hydrochloric acid solution were investigated by Sayyah et al [28][29][30][31][32][33][34][35][36] The orders of the electropolymerization reaction with respect to some reaction parameters such as current density, monomer, and acid concentrations were calculated. The rate laws and the appa-rent activation energies (E a ) of the chemical and electrochemical polymerization process were determined.…”

Electrochemical copolymerization of a binary mixture of pyrrole and 2-amino-4-phenylthiazole on platinum electrode in acid medium was carried out. The kinetic parameters were calculated using ex situ microgravimetric and electrochemical data. The experimentally obtained kinetic equations were R P,W ¼ k W [acid] 1.16 [monomer] 1.85 from microgravimetric data and1.1[monomer] 1.9 from the values of the anodic current density using cyclic voltammetry technique. The apparent activation energy was calculated by the two techniques and is found to be 32.55 and 29.6 kJ/mol from microgravimetric and electrochemical data respectively. The monomer reactivity ratios (r 1 and r 2 ) were calculated according to Fineman-Ross method and the copolymer structure was determined from the obtained data, which is found to be a block copolymer structure. The applications of the prepared copolymer as corrosion protection of mild steel in acid medium are studied.

Electropolymerization of polypyrrole for determination of hydroquinone on screen printed carbon electrode (SPCE) was performed using cyclic voltammetry. Electropolymerization of polypyrrole on SPCE begins with determining the optimum conditions of cyclic voltammetry (working potential, scan rate, number of cycles) and the conditions of solution (pyrrole and KCl concentrations).The working potential were varied at 0 – 0.8; 0 – 0.9; 0 – 1 V. The variation of scan rate were 50, 100, 150 mV/s and number of cycleswere 5, 10,15 cycles. The influence of pyrrole concentration was studied by providing variation of 5, 50, 100 mM. Meanwhile, the KCl concentration were at 0.1; 0.5; 1 M. The SPCE modified with polypyrrole was washed with deionized water and was dried at room temperature. The prepared polypyrrole was analyzed and based on the high anodic and cathodic peak current of the hydroquinone, it is confirmed that the preparation was succefully conducted. The optimum conditions on electropolymerization of polypyrrole areat the working potential of 0 – 0.9 V; the scan rate 100 of mV/s; the number of cyclesis 10, and at thepyrroleconcentration of 50 mM and KCl concentration of 0.5 M. SPCE modified polypyrrole can determine the hydroquinone at the concentration range of 5 – 100 μM with the sensitivity of 0.120 μA/Μm and the detection limit (S/N = 3) of 0.8 μM.

“…Ionisation radiation has also been employed in the development of new technologies for the treatment of waste waters. In particular the degradation of p-CA has been studied by ionising radiation, utilising a 60Co g-rays source: the reaction leads to the formation of NH3, chloride, aldehydes, acids and chlorophenols [17]. In soil remediation, degradation processes based on microbiological and enzymatic activity are also employed.…”

We report a sensitive electrochemical voltammetric method for analyzing p-Chloroaniline using a carbon paste electrochemical (CPE) modified by porous material, such Clay (C). P-Chloroaniline strongly adsorbed on a C-CPE surface and provides facile electrochemical quantitative methods for electroactive p-Chloroaniline (p-CA). Operational parameters have been optimized, and the stripping voltammetric performance has been studied using square wave voltammetry. The peaks current intensity are highly linear, with a good sensitivity of C-CPE. These findings can lead to a widespread use of electrochemical sensors to detect chloroaniline contaminates.
