dc.description.abstract	A highly selective and sensitive phosphate sensor has been fabricated by constructing a crystal disk consisting of variable mixtures of aluminium powder (Al), aluminium phosphate (AlPO4) and powdered copper (Cu). The membrane sensor exhibits linear potential response in the concentration range of 1.0 × 10-1 to 1.0 × 10-6 mol L-1. The proposed sensor also exhibits a fast response time of <60 s. Its detection limit is lower than 1.0 × 10-6 mol L-1. The electrode has a long lifetime and can be stored in air when not in use. The selectivity of the sensor with respect to other common ions is excellent. © 2010 Elsevier B.V. All rights reserved.	en
