/Ortho/ phosphate is absorbed from, and to a limited extent secreted into, the gastrointestinal tract. The transport of phosphate from the lumen of the gut is an active, energy-dependent process, and there are factors that appear to modify the degree of its intestinal absorption. ... Vitamin D stimulates phosphate absorption, and this effect has been reported to precede the action of the vitamin on transport of calcium ion. In general, in adults, about two thirds of the ingested phosphate is absorbed from the bowel, and that which is absorbed from the gut is almost entirely excreted into the urine. In growing children, there is a positive balance of phosphate. Concentrations of phosphate in plasma are higher in children than in adults. This "hyperphosphatemia" decreases the affinity of hemoglobin for oxygen and is hypothesized to explain the physiological "anemia" of childhood. /Phosphates/

Method 3500 Calcium D. EDTA Titrimetric Method for the determination of calcium in polluted water and wastewater samples. When EDTA (ethylenediaminetetraacetic acid or its salts) is added to water containing both calcium and magnesium, it combines first with the calcium. Calcium can be determined directly, with EDTA, when the pH is made sufficiently high that the magnesium is largely precipitated as the hydroxide and an indicator is used that combines with calcium only. Several indicators give a color change when all of the calcium has been complexed by the EDTA at a pH of 12 to 13. Strontium and barium give a positive interference and alkalinity in excess of 300 mg/l may cause an indistinct end point in hard waters. A synthetic sample containing 108 mg calcium/l in distilled water was analyzed in 44 laboratories by the EDTA titrimetric method, with a relative standard deviation of 9.2% and a relative error of 1.9%. /Calcium/|Direct Aspiration Atomic Absorption Spectrometry is used for the determination of calcium in water and wastewater.

NIOSH Method 215. Analyte: Inorganic phosphate. Specimen: Urine. Procedure: Spectrophotometry. For inorganic phosphate this method has an estimated detection limit of 0.06 mg/ml/sample. The presision/RSD is 0.07 and the recovery is not given. The working range is 0.6 to 6 mg/ml for a 25 ul sample. Interferences: Arsenate and silicate will interfere at higher concentrations. Barium, lead, mercury, and silver can interfere by forming a precipitate. /Inorganic phosphate/
