Sodium Iron Pyrophosphate

Amine and Hegsted (1971) obtained similar carbohydrate effects studying iron absorption. Glucose is the most commonly used source of dietary carbohydrate in semipurified diets. Pennell et al. (1976) reported that beta-lactose in place of sucrose reduced the relative biological value of iron as sodium iron pyrophosphate when fed to rats. However, alpha-lactose or glucose in place of the sucrose did not affect the bioavailability of this iron source. Similarly, the source of fat can affect the bioavailability of dietary iron but, the level of dietary fat has no effect (Mahoney et al., 1980). 

A number of investigators have studied the relative bioavailability of iron from various compounds that contained both iron and phosphorus. Three such salts that have been studied extensively are ferric phosphate, ferric pyrophosphate, and sodium-iron pyrophosphate. All three have been listed as Generally Recognized as Safe (GRAS) in the Code of Federal Regulations and have been added to foods in the United States as iron supplements (1). However, only small amounts of two of these phosphorus-containing salts, ferric pyrophosphate and sodium iron... 

This does not mean that the bioavailability of iron from all compounds containing both phosphorus and iron is low. Wood, et al. (12) and Theuer and his associates (7, 8) have found that the bioavailability of iron from sodium iron pyrophosphate and ferric pyrophosphate was greatly improved when the foods containing these salts were processed with heat and pressure (Table II). Such processing did not, however, improve the bioavailability of iron from ferric orthophosphate or ferrous sulfate. The reason for this effect is not known but sugars in the foods may have formed chelates with the iron that facilitated absorption.

During the main period of development a large number of redox systems were investigated. As reductant, in approximate order of development, were diazoether, sugar-iron pyrophosphate, polyamine and sodium formaldehyde sulphoxylate. Amongst the peroxides cumene and p-menthane hydroperoxides have found favour. The SFS system based on sodium formaldehyde sulphoxylate has been particularly useful because of its low cost, ease of preparation and reproducibility. A simplified mechanism for the initiation stage may be given as ... 

Gadolinium is produced from both its ores, monazite and bastnasite. After the initial steps of crushing and beneficiation, rare earths in the form of oxides are attacked by sulfuric or hydrochloric acid. Insoluble rare earth oxides are converted into soluble sulfates or chlorides. When produced from monazite sand, the mixture of sand and sulfuric acid is initially heated at 150°C in cast iron vessels. Exothermic reaction sustains the temperature at about 200 to 250°C. The reaction mixture is cooled and treated with cold water to dissolve rare earth sulfates. The solution is then treated with sodium pyrophosphate to precipitate thorium. Cerium is removed next. Treatment with caustic soda solution fohowed by air drying converts the metal to cerium(lV) hydroxide. Treatment with hydrochloric or nitric acid sol-...
