  • METHODS FOR DETERMINING LOW SULFATE CONCENTRATIONS IN SYNTHETIC UREA SAMPLES, PRODUCED IN A ANUFACTURING PROCESS AND CONTAINING HIGH LEVELS OF IMPURITIES
    Publication number: 20170212086
    Abstract: In one aspect, disclosed herein is a method for determining sulfate concentration in a sample, comprising: a) providing a liquid sample comprising urea and at least one impurity; b) concentrating the liquid sample under conditions effective to reduce the liquid volume; c) forming a dilute sample solution by diluting the concentrated liquid sample of step b) in water; and d) analyzing the dilute sample solution of step c) with ion chromatography to determine if a concentration of sulfate is present in the provided liquid sample of step a); wherein the analyzing of step d) is capable of determining the presence of a sulfate concentration present in an amount less than about 1 ppm.
