Comparison of Several Methods of Determining Inorganic Phosphate in Sea Water

Abstract
Five methods of estimating dissolved inorganic phosphate in sea water are compared. Membrane-filtered inshore water from the Menai Straits was used in the study.Wooster and Rakestraw's method gave higher results than Harvey's procedure. This was caused by some unidentified factor resulting in a non-sensitized reduction of molybdate in the former method.
