Three component Ag2S-PbS-PbWO4 electrodes have been prepared and evaluated for sensitivity to tungstate. The 51.71 : 16.64 : 31.65(w/w%) composition is superior in terms of potentiometric response, stability, rapidity of response and reproducibility. Testing was done over the concentration range 10-1~10-4M WO42- in 0.1F-NH4Ac-NH4OH buffer at pH 8.00 with constant ionic strength. The quality of response is similar to that of corresponding phosphate-sensing electrode. Many common ions interfere.
