The Chemistry of Ethylenediamine Tetra-acetic Acid in Sea Water

Difficulties in the use of ethylenediamine tetra-acetic acid (E.D.T.A) in determining calcium in serum.

The usual methods for the determination of calcium in serum are lengthy procedures. Calcium may be precipitated as oxalate and the oxalate radical estimated by titration with potassium permanganate (Clark and Collip, 1925). The calcium oxalate may be converted to calcium carbonate which is estimated by titration with acid (Trevan and Bainbridge, 1926). Calcium may also be precipitated as calciu...

A study of the effects of ethylenediamine-tetra-acetic acid on myosin adenosinetriphosphatase.

The trior tetrasodium salt of ethylenediaminetetraacetic acid (EDTA or Na EDTA) is a strong chelating agent for heavy metals and the alkaline earth metals, calcium and magnesium. By this action the activity of enzymes which are known to be influenced by calcium or magnesium is altered by the addition of EDTA; e.g., muscle adenylate kinase, which is accelerated by magnesium, is completely inacti...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
