JURNAL POTENSIOMETRI PDF

Title Abstract Author Affiliation. The applications of potentiometric for the determination of the total soil organic carbon has been investigated with CO2 selective electrode as indicator electrode. The principle of the determination is base on the conversion of total soil organic carbon in the sample to CO2 and than the CO2 produced was measured potentiometrically by CO2 selective electrode. The concentration of CO2 was proportional with the total soil organic carbon in the samples.

The presence of aspartic acid, glutamic acid and arginine in solution can be detected by potentiometric method using tungsten oxide electrode in a batch system. Characterization of tungsten oxide electrode used include linear range, limit of detection, sensitivity and reproducibility. Buffer type and concentration effect also studied to optimize the measurement results.

Optimum conditions for detecting arginine was at pH 6. Correlation coefficient was obtained for 0. Glutamic acid has a correlation coefficient of 0.

Aspartic acid has a correlation coefficient of 0. Login Register. Checked By. Indexed By. User Username Password Remember me. Article Tools Print this article. Indexing metadata. How to cite item.

Keywords: Graphene is the ''new star'' material for electrochemical sensing. It has unique mechanical, thermal and electrical Graphene nanoplatelets properties, in addition to its ultra light weight. In the present work we combine for the first time the special features Ion selective electrodes offered by graphene and the advantages of ion selective potentiometric sensors in a single study. We propose two Vilazodone HCl types of sensors, a graphene based carbon paste and a poly vinyl chloride PVC based membrane sensors for Poly vinyl chloride the analysis of Vilazodone hydrochloride in bulk, human plasma and formula milk samples. Electro active agent is Bio analysis an ion- association complex based on coupling of Vilazodone cationic cite with anionic cite of Molybdate ion in a ratio Both sensors were successfully applied to the analysis of Vilazodone HCl in human plasma and formula milk samples showing good recovery percentage values. Graphene based carbon paste sensor shows several advantages over conventional PVC membrane sensor regarding lower limit of detection, faster response time, longer life time and higher selectivity towards target ion.
