| Abstract: | A method for determination of trace Phosphate in water by flow injection spectrophotometry with Molybdophosphate and Malachite Green is described. The optimum concentration range is 0 mg/L - 0.300 mg/L and minimum detectability is 0. 002 mg/L. Operating procedure of the method goes fast, simple and convenient. The method is applied to determination of Phosphate of surface water, ground water, and drink water with satisfactory results. |
