| titleOfInvention | COMPOSITION OF A CHEMICAL SENSOR MEMBRANE FOR DETERMINING THE CONCENTRATION OF MERCURON IONS IN AQUEOUS SOLUTIONS |
| abstract | The invention relates to physicochemical methods of analysis, in particular to a potentiometric method for determining the concentration of mercury ions in solutions. The technical result of the claimed invention is to increase the resource and improve the stability of the chemical sensor for mercury ions in acidic environments. The sensitive element of the mercury sensor is a membrane made of chalcogenide glass. The technical result is achieved by a new high-quality composition of chalcogenide glass. Based on the results, silver selenide was selected as a compound with high ionic conductivity, arsenic selenide was used as a glass former, which are significantly more stable in acidic media compared with silver sulfide and arsenic sulfide, and mercury iodide as an electrode-active substance, which provides high the stability of the membrane material and, as a result, the best characteristics of the sensitivity and accuracy of determination of mercury ions. The ratio of chalcogenide glass components is as follows: mercury iodide (15-35 mol%) - a potential-determining substance; silver selenide (15-35 mol.%) - a compound with high ionic conductivity; arsenic selenide (50 mol%) is a glass former. |
