Abstract

A novel polyvinyl chloride (PVC) matrix membrane sensor responsive to inorganic phosphate ion was described. The working pH range is 4.0-6.0 and the response time is about 7.5 min. Under the optimum condition, the sensor displayed a good linear response for H2PO4-anion over the concentration range 6.00-15.00 μg/ml with a limit detection of 0.02 μg/ml. The life span of membrane sensors is 90-120 days, and it could be used for 60 times with several supplements of the fluorescent probe. Applied for the determination of phosphate at levels of 8.00-12.00 μg/ml in artificial seawater, the recoveries ranged from 96.6% to 103.8%, and the relative standard deviation was less than 4%.
