A colorimetric micromethod is proposed for determination of phosphates in various materials (biological substances, pharmaceuticals and food). It is based on precipitation of magnesium uranyl phosphate, which is then dissolved in dilute sulphuric acid, and the uranyl ion is determined spectrophotometrically via the dark red colour of uranyl ferrocyanide. The sensitivity is 0.01 mg of P, and the average error 1%. The method is very simple and applicable to many types of sample.
