Abstract This thesis examined the redox behaviors of thallous chloride in the absence and presence of di ethyl amino ethyl cellulose by applying cyclic voltammetry in 0.1M HNO3 as a supporting electrolyte at 298.15K. The glassy carbon electrode was used as a working electrode, platinum wire as an auxiliary electrode, and silver/silver as a reference electrode. The electrochemical demeanor was studied at a potential range from 1.5 V to -1.5 V by the use scan rate of 0.1 V/S. The oxidation wave and the reduction wave were studied and compared in the presence and absence of di ethyl amino ethyl cellulose at the same temperature. The effect of different scan rates from (0.1 to 0.01) V/S was also studied for thallous chloride in the absence and presence of di ethyl amino ethyl cellulose. The ratio between the di ethyl amino ethyl cellulose concentration to the thallous chloride concentration was also studied. This thesis also examined the cyclic voltammetry study of potassium permanganate at a potential range from 1.25 V to -1 V by the use of 0.1 M HNO3 as a supporting electrolyte in the absence and presence of cellulose acetate. The two oxidation wave and the two reduction wave were studied and compared in the presence and absence of cellulose acetate and the influence of different scan rates (0.1, 0.05 & 0.02) V/S was also studied for potassium permanganate in the absence and presence of cellulose acetate. The ratio between the cellulose acetate concentration to the potassium permanganate concentration was also studied. This thesis also examined the cyclic voltammetry of BaCl2 in 0.1M KCl at a potential range from 1.5 V to -1.5 V in the absence and presence of amoxicillin at 297.95 K. The effect of different scan rates in the presence of amoxicillin (0.1, 0.05& 0.01)V/S was also studied. The results of the conductivity data obtained were analyzed to calculate the association constant, association thermodynamic parameters and complex formation constant from the interaction between (thallous chloride with di ethyl amino ethyl cellulose - potassium permanganate with cellulose acetate) and the suggestion of the electrochemical reaction mechanism for both. |
