Web11 nov. 2008 · The method was based on the world wide accepted procedure of Murphy and Riley, using ascorbic acid as reductant, allowing the use of the common automated systems with minor adaptations. A segmented flow system was built using a single 700 mm long dialysis path. WebThe method detection limit (3 × standard deviation of blank, n = 10) was 8 nM and the calibration curve was linear over a range of 10–400 nM (r2 = 0.997). The molar absorptivity was 1.26 × 105 L mol−1 cm−1 at 600 nm with the background correction at 530 nm. The precision of method was 3.4% at 50 nM and 2.4% at 100 nM orthophosphate (n ...
WebThe Murphy-Riley method involves an oxidation-reduction reaction in which phosphorus is reacted to form a chromogen-mineral complex that can be measured with a spectrophotometer at a visible wavelength.
