MEMBRANE OF LEAD-SELECTIVE ELECTRODE Russian patent published in 1996 - IPC

Abstract RU 2054666 C1

FIELD: ionometry. SUBSTANCE: membrane composition involves the electrode-active component, plasticizer and polyvinyl chloride. Membrane has additionally lipophilic addition - tetrakis-(4-fluorophenyl) potassium borate and electrode-active component - 1,8-bis-[2-(diphenylphosphinylmethyl)phenoxy]-3,6-dioxaoctane at the following ratio of components, wt.-%: electrode-active component 1-2; plasticizer 63-72; lipophilic addition 0.1-2.0, and polyvinyl chloride - the rest. The use of membrane of indicated composition ensures to increase the coefficient of selectivity in the presence of silver ions from 10⁺¹ to 10^-1 in the presence of copper ions from 10^-1 to 10^-3. EFFECT: enhanced selectivity to lead ions in the presence of some heavy metals. 2 tbl, 1 dwg
