Applications of Chromatography in the Analysis of Inorganic Materials
The role of separations in inorganic analysis is discussed and the advantages of various chromatographic techniques are stressed. Major separation methods include solvent extraction, column extraction chromatography, gas chromatography of volatile metal chelates, ionexchange chromatography, and column chromatography employing chelating resins and non-ionic sorptive resins. The use of each of th...
متن کاملAdvances in the determination of inorganic anions by ion chromatography.
The time period covered for this review includes articles published from 1997 to 1999, with the addition of a few classic references. The purpose of the review is to include the most relevant works from each topic area of the determination of inorganic anions by ion chromatography, including new sample pretreatments, new separation methods, new detection systems and the latest applications in t...
متن کاملMetabolism of Inorganic Pyrophosphate. I. Microsomal Inorganic Pyrophosphate Phosphotransferase of Rat Liver.
The formation of large amounts of inorganic pyrophosphate as a by-product of numerous synthetic reactions in nearly all living tissues makes the metabolic reactions of this compound of interest. Rapid hydrolysis to orthophosphate is presumed to be the fate of most inorganic pyrophosphate but the possibility of the conservation and utilization of some of the energy of this compound has been a su...
متن کاملUtilization of inorganic sulfate by rumen microorganisms. I. Incorporation of inorganic sulfate into amino acids.
The ability of rumen microbiota to incorporate inorganic sulfate into cystine and methionine was suggested by Loosli et al. (1949) and demonstrated by Block et al. (1951) through use of radioactive sodium sulfate. The significance of this incorporation as applied to ruminant nutrition has been discussed by Davis et al. (1954). Formation of microbial protein in the rumen of cattle is accompanied...
متن کاملOrganic and inorganic selenium: I. Oral bioavailability in ewes.
Although the essentiality of dietary Se for sheep has been known for decades, the chemical source and Se dosage for optimal health remain unclear. In the United States, the Food and Drug Administration (FDA) regulates Se supplementation, regardless of the source of Se, at 0.3 mg of Se/kg of diet (as fed), which is equivalent to 0.7 mg of Se/d or 4.9 mg of Se/wk per sheep. The objectives of this...
