Abstract
An improved Strickland and Parsons' method, in which silicate correction is made, is described for the colorimetric determination of phosphate in seawater. Silicate correction is made by subtracting the value of 0.025 (C/100)2, whereC is silicate concentration (µg atoms 1−1), from the observed phosphate concentration. The relative standard deviations are 2 % at the 1 µg atom PO 3−4 −Pl−1 level and less than 1 % at the 3 µg atoms PO 3−4 −Pl−1 level in seawater.
