Determination of phosphate by titration
WebAfter 9 minutes, the corrected colorimeter reading was 38.0mm. The calculation follows. 80 + 38.0 = 2011mg. of phosphorus per 100 cc. From this must be sub- tracted a … 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.
