Zirconyl-alizarin blue s complex a spectrophotometric study
Analytica Chimica Acta, 1958Abstract Alizarin blue S in 0.5N hydrochloric acid and 10% acetone gives a coloured complex with zirconium salts, which is used for the estimation of zirconium.

Uranyl-alizarin red-s complex.a spectrophotometric study
Analytica Chimica Acta, 1955Abstract From spectrochemical studies on the blue complex resulting from uranyl and alizarin-S, it has been shown that a compound in the stoichiometric ratio 1:1 of uranyl and reagent is formed. The compound is stable at pH 8.2. The peaks of absorption of the reagent at 520 mu; and of the uranyl compound at 570 mμ have been accounted for, applying ...

Pink Staining of Pernicious Anemia Megaloblasts by Alizarin Red S
American Journal of Clinical Pathology, 1974The anthraquinone dye alizarin red S produced pink staining of the cytoplasm of proerythroblasts and megaloblasts in 8 patients with untreated pernicious anemia. This pink staining was not observed in erthyroid precursors from severely folatedeficient individuals, or from a variety of other types of anemic or normal controls.

Spectrophotometric study of the complex of lanthanum and alizarin Red S
Talanta, 1961Abstract The complex of lanthanum with alizarin Red S in acetate medium has been studied spectrophotometrically since it appears to be promising for the determination of the chemical yield in radioactivation analysis of rare earth elements. At pH 4.6 (acetate buffer) the molecular ratio lanthanum: alizarin Red S is 1:2.

Comparative efficacy of differing modes of administering alizarin red S in dogs
Oral Surgery, Oral Medicine, Oral Pathology, 1969Abstract Although it has been widely accepted that the use of alizarin red S in vital staining techniques is an accurate method of measuring bone growth, we have found the staining to be less than sharp or intense via all routes of administration. Furthermore, the literature does not reflect the serious toxic and untoward effects which frequently ...

Orientation of adsorbed alizarin red S on hydroxyapatite.
Calcified tissue international, 1983Adsorption isotherms of alizarin red S on hydroxyapatite were supplemented with additional data to provide a simple model of adsorption. The model treats the adsorbing surface as a mosaic of unit cell a-c faces which have an area of 65 A2 each. The adsorbate of the model has molecular dimensions consistent with a 1:1 relationship between adsorbate and ...

Composition and Stability of Lead‐Alizarin Red S Chelate
Journal für Praktische Chemie, 1965AbstractThe composition and stability of the red coloured complex of lead‐Alizarin Red S chelate (λmax490mμ) have been determined using the mole ratio method and the slope ratio method. The ratio of lead to Alizarin Red S has been determined to be 1:1. The chelate is stable between pH 5.4 and 8.2. The value of formation constant is 6.0.

The determination of zirconium in mineral rutile with Alizarin red S
The Analyst, 1968A colorimetric procedure has been developed for the determination of the zirconium oxide content of rutile. A fusion with potassium hydrogen difluoride enables the rutile to be brought into solution rapidly and eliminates the task of filtering off silica. The zirconium is separated from the titanium by a phosphate precipitation, but the interference of
