Abstract
A method has been developed that permits the determination of phosphorus concentrations down to 0·04 µM in nutrient solutions that contain silicon. The problem of silicon interference is eliminated by use of ethyl acetate as a selective extractant for the yellow molybdophosphoric acid prior to its reduction to heteropoly blue (molybdenum blue).Keywords
