METHOD OF DETERMINING PHOSPHATE CONCENTRATION IN A WATER SAMPLE

原文（中国語）

A method for determining a phosphate concentration in a water sample. The method includes providing the water sample, determining a first phosphate concentration of the water sample via a molybdenum yellow method or via a variant of the molybdenum yellow method at a first temperature, and, if the first phosphate concentration is falls within a specified range, determining a corrected phosphate concentration of the water sample via the molybdenum yellow method or via the variant of the molybdenum yellow method at a second temperature.
