INFLUENCE OF ZnCl2 CONCENTRATION ON THE SELECTIVITY OF A Zn(NCS)4²--SELECTIVE ELECTRODES AND ITS APPLICATION FOR DETERMINATION SCN- IONS IN INDUSTRIAL SOLUTIONS
The influence of the background concentration of ZnCl2 on the selectivity of Zn(NCS)4(2-)−SE based on QAS to SCN- is studied. The introduction of ZnCl2 into a solution fixes zinc released from the membrane in the form of thiocyanate complex. A high selectivity of the Zn(NCS)4(2-)−...
