FIELD: physical-chemical methods of analysis, production of membranes of solid ion-selective electrodes utilized in analysis and tests of liquid media under laboratory and production conditions. SUBSTANCE: composition of membrane of ion-selective electrode includes compound based on metal chalkogenide, namely, titanium dichalkogenide composed of MxTiX2, where M is Li, Na, K, Cs, Ag, Mg, Ca, Sr, Ba, Hg, Fe, Co, Ni, Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tu, Yb, Lu, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W; X is S, Te, Se; 0,25>=x>=0,05; and additionally injected with inert polymer binder with following proportion of components, per cent by volume: titanium dichalkogenide composed of MxTiX2, where M is Li, Na, K, Cs, Ag, Mg, Ca, Sr, Ba, Hg, Fe, Co, Ni, Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tu, Yb, Lu, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W; X is S, Te, Se; 0,25>=x>=0,05; is 20.0- 80.0; polymer binder is 80.0-20.0. Composition of ion-selective electrode can have polystyrene in the capacity of polymer binder. EFFECT: development of composition of membrane of ion-selective electrode enabling content of metals in solutions of wide spectrum to be determined with high degree of accuracy. 2 cl |
