WebThe single-point standard addition method was used in the determination of phosphate by the molybdenum blue method. A 2.00-ml urine sample was treated with molybdenum blue reagents to produce a species absorbing at 820 nm, after which the sample was diluted to 100.00 ml. A 25.00-ml aliquot gave an absorbance of 0.428 (solution 1).
