AbstractSpectrophotometric determination of total phosphorus in meat samples was modified using the molybdenum blue reaction with the following reducing agents: ascorbic acid (AA), hydrazine sulphate (HS), and mixture of hydroquinone and hydrazine sulphate (HHS). Proposed methods were validated by evaluation of statistical parameters such as: linearity, sensitivity, limits of detection (DL) and quantification (QL), precision, and accuracy, against the standard and malachite green (MG) modified procedures and by applying food certified materials. The values of within-day and between-days precision in meat samples for all tested reducing agents were better than 3.4 % and 4.2 %, respectively. The recoveries for CRMs analyses were between 92 % and 102.3 %. Obtained results suggest usefulness of the hydroquinone and hydrazine sulphate mixture in the determination of phosphorus ions.

Abstract A procedure is described for the automated simultaneous determination of serum calcium and phosphorus. Calcium is assayed fluorometrically; phosphorus is determined spectrophotometrically by the molybdenum blue reaction in an improved flow system with a more sensitive reducing agent.

Serum Inorganic Phosphate

Several current techniques for the determination of serum inorganic phosphate in the presence of proteins are shown to have important disadvantages. An improved manual micromethod is described in which proteins are kept in solution by the use of sodium lauryl sulphate and the phosphate determined by the molybdenum blue reaction. The procedure has been adapted for the Technicon AutoAnalyzer and the Vickers D-300 and M-300, and has been shown to give very good precision in routine use.
