A PVC menmbrane based on o -Vanillin -2 -aminophenol was prepared for construction of Cu （ Ⅱ） - selective electrode. The electrode exhibted nernstian response to Cu（Ⅱ）over a range of 1.00 × 10^-5 - 1.00× 10^-2 mol/L, with a detection limit of 6.38 × 10^-6 mol/L. The response time of the electrode was less than 30 s, and it also exhibited good selectivity for Cu （ Ⅱ） over a wide variety of metal ions. The electrode was used to determine the copper contents in the wastewater, and the result was excellent.
