Abstract
Abstract A simple and precise colorimetric method of determining phosphate in aqueous solutions containing nitrilotriacetic acid (NTA) or ethylendiaminetetraacetic acid (EDTA) is described. It involves precipitation of the NTA or EDTA by acidification to pH 1.5 and colorimetric determination of the phosphate in the filtrate by a heteropoly blue method. The method is sensitive and accurate, and it permits determination of microgram amounts of phosphate in samples of aqueous solutions containing up to 300 mM of NTA and (or) EDTA.
