The chelating agent ethylenediaminetetraacetate (EDTA) is not degraded by conventional biological and physicochemical methods for the treatment of wastewater and the purification of drinking water. Of the measurable organic compounds it is the one present at the highest concentration in many surface and drinking waters.

Talanta, 1997
In this paper, analytical techniques for the determination of ethylenediaminetetraacetic acid (EDTA) and diethylenetriaminepentaacetic acid (DTPA) are reviewed. These compounds, especially EDTA, are used as metal chelating agents in several industries. As they are likely to be poorly degraded in waste water treatment plants, significant amounts of EDTA

Spectrophotometric determination of EDTA
Talanta, 1971Both iron(III) and its EDTA complex in 0-1N H(2)SO(4) medium absorb in the ultraviolet region of the spectrum, with absorption maxima at 305 and 258 nm respectively. EDTA can thus be determined by addition of excess of Fe(III) and measurement of the absorbance at the two wavelengths. An EDTA concentration as low as 10(-6)M can be determined with a fair

Activation of rabbit kidney fructose diphosphatase by Mg-EDTA, Mn-EDTA and Co-EDTA complexes
Archives of Biochemistry and Biophysics, 1973Abstract Purified rabbit kidney fructose diphosphatase requires both a free cation and a metal-chelate when assayed at pH 8 or below. In the presence Mg2+ or Mn2+, effective metal chelates were Mn(II)-EDTA, Mg(II)-EDTA, and Co(III)-EDTA. With Mg2+ as the cation the affinity of the enzyme for Mn(II)-EDTA or Mg(II)-EDTA was approximately the same, and ...

EDTA-Dependent Lymphoagglutination
Laboratory Hematology, 2008Lymphoagglutination is an extremely rare EDTA-dependent phenomenon and is far less frequent than neutrophil agglutination. We describe 6 new cases and briefly review the literature on lymphoagglutination.

REACTIONS AND MOVEMENT OF EDTA AND ZN EDTA IN SOILS
Canadian Journal of Soil Science, 1972A miscible displacement technique was used to study the movement of EDTA and Zn EDTA in soils. EDTA moved quite readily through the soil. The EDTA from a Zn EDTA complex also moved readily through the soil cores; however, the Zn was replaced to a large extent. If the Zn EDTA complex remained intact, then it moved through the soil with the liquid phase.

EDTA-Dependent Leukoagglutination
American Journal of Clinical Pathology, 1990Leukopenia (WBC 1.9 x 10(9)/L) was reported from an automated cell counter (TOA E-5,000, Symex) on a patient blood sample collected in ethylene diamine tetracetic acid (EDTA). Leukocyte aggregates of 30-50 cells were seen on the peripheral blood smear. Blood samples collected in heparin, citrate, and EDTA had white blood counts (WBC) of 8.1, 8.1, and 2.

EDTA-Induced Pseudothrombocytopenia
Southern Medical Journal, 1992A 45-year-old man was admitted to the hospital because of unstable angina pectoris. During the wait for coronary artery bypass surgery, the platelet count gradually decreased from 154,000 to 20,000/mm3, without hemorrhagic manifestations. Medications were discontinued and surgery was postponed.

An evaluation of EDTA in endodontics
Oral Surgery, Oral Medicine, Oral Pathology, 1974Abstract The purpose of this investigation was to determine the chemical self-limiting property of the chelating agent, EDTA, by a gravimetric method. It was shown that a determinable quantity of dentin can be chelated by a known quantity of EDTA. It was also found that an excess of EDTA will react with 73 per cent of the available inorganic dentin ...

Agglutination of an EDTA Blood Sample Caused by an EDTA-Dependent Panagglutinin
American Journal of Clinical Pathology, 1985A novel example of an EDTA-dependent panagglutinin is described. A blood sample drawn into EDTA for a routine hematologic workup demonstrated strong agglutination due to EDTA-dependent panagglutinins. Previous examples have been detected because of discrepant ABO results.
