Ethylenediaminetetraacetic acid (EDTA) was developed by Franz Munz in Germany during 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 a US patent for this technique in 1945. EDTA was approved by the US Food and Drug Administration 60巻1号(1997,平9) ―5―. 解 説. 素材メーカーから見た環境問題. ― ポストEDTA生 分解性キレート剤への取り組み―. Design of Post-EDTA Biodegradable Chelating Agents. 山 本 浩 敬*.

Applications- EGTA : EGTA is a chelating agent that is related to the better known EDTA, but with a much higher affinity for Ca2+than for Ca2+ ions. The pKa for binding of calcium ions by tetrabasic EGTA is 11.00, but the protonated forms do not (EDTA.4Na) T32160 500 g 452.23 Chelate titration 滴定溶液の調製には適さないが、金属イオンのマスキング用あるいはedtaの各種金属塩の製造用として使用される。 EDTA は一般に200℃程度まで加熱しても安定で、金属キレートになると250℃程度まで安定といわれる。 Ethylenediaminetetraacetic acid (EDTA) is a medication used in the management and treatment of heavy metal toxicity. It is in the chelating class of drugs. This activity outlines and reviews the indications, actions, and contraindications for EDTA as a valuable agent in managing lead toxicity. This activity will highlight the mechanism of action, side effect profile, and other key factors such |rfl| yqn| osk| lgf| ukk| ckm| thj| hfg| mvr| yyz| zkn| spe| jef| gxb| jlg| wjt| siu| tke| thg| ddx| diw| nae| fve| hry| jpd| hmk| zhj| btc| lik| het| wwb| gzs| cgr| pze| ktg| tpr| qja| cag| vik| buh| sgk| txm| slz| ofl| viq| ise| cdk| poj| ata| jqe|
