Disodium Ethylenediaminetetraacetate

Calcium and magnesium can be titrated readily with disodium ethylenediaminetetraacetate, with Eriochrome Black T as the indicator. The solution is buffered at pH 10.0. Certain metal ions interfere with this procedure by causing fading or indistinct end points. Cyanide, sulfide, or hydroxjiamine can be used to eliminate or minimise the interferences. [Pg.231]

For the same purpose, Kelly and Bryske used paper impregnated with 0.1N disodium ethylenediaminetetraacetate (EDTA) and two mobile solvents the organic phase from a mixture of n-butanol, ammonia, water (4 1 5) and the organic phase from a mixture of n-butanol, acetic acid, water (4 1 5). Disodium EDTA (0.1N) works as well as Mcllvaine s buffer when it is used to treat the paper in the method of Walton et al. (49). A circular paper chromatographic method also using paper dampened with Mcllvaine s buffer (pH 4.5) was reported by Urx et al. (50). They used a mixture of chloroform and n-butanol (4 1) as the mobile solvent. [Pg.125]

Specifically, disodium ethylenediaminetetraacetate (EDTA) reacts with polyvalent metal ions to result in the formation of a fairly stable water-soluble complex, or a chelate compound. [Pg.162]

The solvent contains 0.0025 M Na,HPOJf 0.0050 M NaH2P04 and 0.0010 M disodium ethylenediaminetetraacetate as a chelating agent far divalent cations. Such a low value of counter-ion concentration as this is adequate for preventing aggregation of denatured DNA molecules. [Pg.270]

N EDTA/0.2 N TRIS Solution Transfer 18.6 g of disodium ethylenediaminetetraacetate (EDTA) and 6.05 g of tris (hydroxymethyl)aminomethane (TRIS), both accurately weighed, into a 250-mL beaker. Add 200 mL of hot, deionized water, and stir until dissolved. Adjust the pH to 7.5 to 7.6 by adding 5 N sodium hydroxide. Cool the solution, and adjust the pH to 8.0 with 5 N sodium hydroxide. Transfer the solution into a 250-mL volumetric flask, and dilute to volume with deionized water. Mix well, and store in a plastic container. [Pg.81]

The composition of the THF complexes of the lanthanide trichlorides is established by dissolution of a weighed amount of each compound in water and determination of chloride potentiometrically with aqueous silver nitrate. Analysis for the lanthanide is effected by titration with disodium ethylenediaminetetraacetate using xylenol orange indicator after appropriate buffering of the solution.The IR spectra of all the trichlorides show intense bands at 1020 and 880 cm" (see below), indicative of coordinated THF. ...
