Recipe for ferric salts of ethylenediaminetetraacetic Acid.
The supply of iron to plant roots was one of the main problems in water culture until about 1950. The main source of iron was originally ferrous sulfate, already used by Sachs (9). It had to be supplied almost daily to the nutrient solution as it precipitates gradually. Some improvement was obtained with organic compounds, mainly ferric citrate, introduced by Gile and Carrero (4). The favorable...
متن کاملEthylenediaminetetraacetic acid in endodontics
Ethylenediaminetetraacetic acid (EDTA) is a chelating agent can bind to metals via four carboxylate and two amine groups. It is a polyamino carboxylic acid and a colorless, water-soluble solid, which is widely used to dissolve lime scale. It is produced as several salts, notably disodium EDTA and calcium disodium EDTA. EDTA reacts with the calcium ions in dentine and forms soluble calcium chela...

Ethylenediaminetetraacetic acid (EDTA) was developed by Franz Munz inGermanyduring the 1930s as an alternative to citric acid. About the same time, Frederick Bersworth synthesized EDTA in the United States using a different technique. He obtained aUSpatent for this technique in1945. EDTAwas approvedby the US Food and Drug Administration (FDA) as a food additive in 1947. Since the early 1950s, E...
متن کاملStudies of Cardiac Muscle with a High Permeability to Calcium Produced by Treatment with Ethylenediaminetetraacetic Acid
Thin strips of frog ventricle were isolated and bathed for 15 min in a solution containing 140 mM KCl, 5 mM Na(2)ATP, 3 mM EDTA, and 10 mM Tris buffer at pH 7.0. The muscle was then exposed to contracture solutions containing 140 mM KCl, 5 mM Na(2)ATP, 1 mM MgCl(2), 10 mM Tris, 3 mM EGTA, and CaCl(2) in amounts to produce concentrations of free calcium from 10(-4.8)M to 10(-9)M. The muscles dev...
