Synthesis of Polymer Sensor for Detection of Phosphate in Water

Worawit Wongniramaikul and Aree Choodum
Abstract—A colorimetric polymer sensor was successfully developed for the detection of phosphate in water. Potassium antimonyl tartrate, ammonium molybdate, ascorbic acid and sulfuric acid were entrapped within the polyvinyl alcohol (PVA) hydrogel matrix and acted as the colorimetric reagent. The PVA sensor was fabricated within a micro-PCR tube to which the sample solution could be directly added for in-tube detection. This made the developed sensor small and easy to carry on field. The optimum condition for sensor synthesis was determined in this research by using the digital image analysis. They are found at 0.6 g/L potassium antimonyl tartrate, 14.4 g/L ammonium molybdate, 5.28 g/L ascorbic acid, 0.05 mg/L sulfuric acid and 15 min reaction time.

Index Terms—Hydrogel sensor, phosphate detection, polymer sensor.
