Determination of phosphate by titration
Websulfite determination proved to be an effective alternative. The addition of 0.1% SDS into the carrier of 0.1 M phosphate buffer (pH 8) can prevent electrode fouling. The SIA manifold for sulfite analysis is simple and the sensitivity of the method is good. The sensitivity of the method can be changed easily by changing the sample volume.

WebTHE SPECTROPHOTOMETRIC DETERMINATION OF PHOSPHATE IN NUCLEAR MATERIALS INTRODUCTION Phosphorus analyses of uranium and plutonium product solutions are required in order to ensure that the final product will meet the desired specifications. Phosphate analyses may be used to obtain a portion of the total phos- WebA new complexometric method for the determination of phosphorus in organic compounds is described. After combustion in an oxygen-flask, phosphorus is precipitated as cereus phosphate. The excess cereus ion is back-titrated at pit 6--7 with EDTA in the presence of methylthymol blue or xylenol orange indicators.
