A new low cost vanadium sensor developed by immobilizing a direct indicator dye to porous and transparent acetylcellulose film. This sensor was fabricated by binding gallocyanine to a cellulose acetate film that had previously been subjected to an exhaustive base hydrolysis for 24h and increase the porosity of the membrane. The cellulose membrane were immediately treated with mixture of 1.00 % (W/V) thiorea and 0.70% (W/V) poly (vinyl alcohol) solution for 48 h at 25°C. The cellulose membrane were separately treated with 0.1% (W/V) solution of gallocyanine at 25 °C with magnetic stirring of the solution for 14h. After washing, the films were dried at 45 °C for 20 min. Then the membrane have good durability (> 6 months), a short response time (
