EDTA trisodium

The aqueous process solution containing sodium thiocyanate with impurities was provided by a local industry. All the membrane modules, pressure vessels, and accessories for the nanofiltration pUot plant used in this study were purchased from Permionics Membranes Pvt. Ltd. (Baroda, India) and assembled in the laboratory. Citric acid, tetra sodium salt of ethylene diamine tetraacetic acid (EDTA), trisodium phosphate (TSP), and sodium metabisulfite for cleaning and maintenance of the membranes were procured from Lob a Chemie (Mumbai, India).

In mammals, phenobarbital and phenytoin increase serum ceruloplasmin concentrations (Aaseth and Norseth 1986). Chronic copper poisoning in sheep is exacerbated when diets contain heliotrope plants (Heliotropium sp., Echium spp., Senecio sp.). Aggravated effects of the heliotrope plants include reduced survival and a twofold to threefold increase in liver and kidney copper concentrations when compared to control animals fed copper without heliotropes (Howell et al. 1991). Rats given acutely toxic doses of 2,3,7,8-tetrachlorodibenzo-para-dioxin had elevated concentrations of copper in liver and kidney because of impaired biliary excretion of copper (Elsenhans et al. 1991). Morphine increases copper concentrations in the central nervous system of rats, and dithiocarbam-ates inhibit biliary excretion (Aaseth and Norseth 1986). In human patients, urinary excretion of copper is increased after treatment with D-penicillamine, calcium disodium EDTA, or calcium trisodium diethylenetriamine penta acetic acid (Flora 1991).

Ethylenediamine tetraacetic acid (EDTA) [60-00-4] (Sequestrene), an anticoagulent at 1 mg of the disodium salt per mT. blood, complexes with and removes calcium, Ca2+, from the blood. Oxalate, citrate, and fluoride ions form insoluble salts with Ca2+ and chelate calcium from the blood. Salts containing these anticoagulants include lithium oxalate [553-91-3] LyC204, 1 mg/mL blood sodium oxalate [62-76-0] Na2C204, 2 mg/mL blood potassium oxalate monohydrate [6487-48-5] H20, 2 mg/mL blood sodium fluoride [7681-49-4] NaF, 2 mg/mL blood trisodium citrate...

Precipitating builders, such as sodium carbonate. Na>CO . are also used, but lo a much lesser extent, since Ihe precipitate formed can iiself deposit on ihe surface to be cleaned unless special washing procedures are followed. Other chelating builders than phosphates, such as trisodium nitrilotriacelate (NTA), tetrasodium elhylenediamine tetraacetate (EDTA). and other polycarboxylates. have also been used in small to moderate quantities, but questions concerning their safely, efficacy, or economics have to dale prevented major displacement of the phosphates. 

Avoidance of interference of other milk constituents with measurements is also of importance for example, dissociation of casein micelles by calcium-chelating agents, such as trisodium citrate or ethylenediamine tetra-acetic acid (EDTA), may used to avoid interference of the micelles in particle size measurement, while clusters of fat globules can be disrupted by adding a low level of sodium dodecyl sulphate (SDS).

PRP and PPP preparation. If rats or mice are used, they are anaesthetized by an i.p. injection of sodium pentobarbital (50 mg/Kg), and blood is drawn into heparin (5 units/ml final) or citrate/dextrose (final concentration 0.38% and 0.48% (wt/vol), respectively) anticoagulant from the dorsal aorta or by heart puncture, with a 22-gauge needle (the choice of heparin as anticoagulant appears to be more appropriate, because chelation of divalent cations by trisodium citrate or EDTA might affect platelet-tumor cell interaction). Blood is then diluted with an equal volume of 0.9% NaCl, and centrifuged for 7 min at 400 x g on preformed gradients of 70% Percoll containing 0.9% NaCl. The yellowish supernatant is the PPP, while PRP forms a white band between PPP and the percoll layer. Platelets in PRP are counted with a Coulter counter and diluted with PPP to a concentration of 10 /ml. PPP is a source of prothrombin, and should thus be included in the assay. 

Note A number of salts of EDTA are available with uses identical or similar to the acid. The USP salts are called edetates (calcium disodium, disodium edetates) others are usually abbreviated to EDTA (tetrasodium, trisodium EDTA). Other salts, known chiefly under trademark names, are the sodium ferric, dihydrogen ferrous and arange of disodium salts with magnesium, divalent cobalt, manganese, copper, zinc, and nickel.
