The effect of sodium N-4-methoxybenxyl D-glucamine-N-carbolithioate (MeOBGDTC) on the urinary elimination of cadmium and several endogenous metals was determined in rats in contrast to calcium disodium ethylenediamine tetraacetate (Ca-EDTA).
The effect of sodium N-4-methoxybenxyl D-glucamine-N-carbolithioate (MeOBGDTC) on the urinary elimination of cadmium and several endogenous metals was determined in rats in contrast to calcium disodium ethylenediamine tetraacetate (Ca-EDTA).
The results indicates that the reaction temperature is 80℃,the dosage of ammonium peroxydisulfate is 1.6%,the disage of disodium ethylene diamine tetraacetate is 0.12%,the reaction time is 8h,water consumption of initiator is 9 ml,the removal rate of turbidity may achieve 94.9%.
②The orthogonal experiment( L16(45)) of bluestone, zinc sulfate, disodium ethylenediamine tetraacetate, temperature and time was done. We found the result that 1.00% zinc sulfate add 0.01% bluestone add 0.015% disodium ethylenediamine tetraacetate was the best protecting-color liquid,in which 70 ℃and four minutes is the best temperature and time.
② 硫酸铜、硫酸锌、EDTA-2Na、温度和时间的L16(45)正交试验结果为:在1.00%硫酸锌+0.01%硫酸铜+0.015EDTA-2Na 护色液中,70℃处理4min 为最优组合,其叶绿素含量最高。
Acrylamide-sodium acrylate copolymer used as flocculant was synthesized by inverse emulsion polymerization,in which mole ratio of comonomers was 1 ∶1.Effect of monomer concentration,oxidant concentration,emulsifier concentration,HLB value of polymerization system,oil phase/water phase volume ratio,disodium ethylene diamine tetraacetate (EDTA disodium)dosage on intrinsic viscosity of copolymer were investigated.
Dimethyldiallylammonium chloride (with mass fraction of 65%) is chosen as the monomer,ammonium peroxydisulfate as the initiating agent,disodium ethylene diamine tetraacetate as the addition agent,poly-dimethyldiallylammonium chloride is synthesized through aqueous solution polymerization.
The effects of copper disodium ethylenediamine tetraacetate (Cu-EDTA) and disodium ethylenediamine tetraacetate (Na2-EDTA) on tissue and peritoneal mast cells of Wistar rats were compared.
Wistar rats were intravenously injected with copper disodium ethylenediamine tetraacetate (Cu-EDTA, a new mast cell discharger) and in varied intervals with 65Zn.
Eight cases of chronic lead poisoning in iron-smelting furnacemen were reported,Their history of exposure were obvious, and their clinical manifestation were shown to have neurasthenia syndrome, weakness of the extensor muscles, increase of urinary and blood lead levels. Most of them had their urinary lead content exceeded 1 mg/day after drive lead test. All cases were treated with intravenous injection of calcium disodium ethylenediamine tetraacetate, seven to nine courses in total, resul...
The effect of sodium N-4-methoxybenxyl D-glucamine-N-carbolithioate (MeOBGDTC) on the urinary elimination of cadmium and several endogenous metals was determined in rats in contrast to calcium disodium ethylenediamine tetraacetate (Ca-EDTA). After exposed to cadmium chloride(4.448μmol Cd(2+) /Kg /day. 4 weeks, i. p). rats were given MeOBGDTC and Ca-EDTA(889. 600μmol/Kg/day, 5 times.i. p). The results showed that both Ca-EDTA and MeOBGDTC significantly increased the urinary excretion of cad...
Disodium ethylenediamine tetraacetate is a good sequesterant.This paper introduces its structuce, properties, quality standard and function.The property of antimicrobial was studied and the cooperative effect with potassium sorbate was also discussed.
