A novel Pt/ACF (Pt supported on activated carbon fibers) electrode was successfully prepared with impregnation and electrodeposition method. Characterization of the electrodes indicated that the Pt/ACF electrode had a larger effective area and more active sites. Electrochemical degradation of ethylenediaminetetra-acetic acid (EDTA) in aqueous solution with Pt/ACF electrodes was investigated. Th...

Biliary calcium may be a nucleating agent in cholesterol cholelithiasis. A study was designed to determine the effect of binding of ionised calcium on in vitro nucleation time. Ultracentrifuged and microscopically clear gall bladder bile from cholesterol gall stone patients was divided into two aliquots. One aliquot served as control and ionised calcium was bound in the second aliquot by additi...

1 The effects of the disodium salt of ethylenediamine tetra-acetate (EDTA) and 1, 2, bis, 2 aminoethoxyethane-NNN'N'-tetra-acetic acid (EGTA) on renin secretion and vascular resistance were studied in the isolated perfused kidney of the rat. 2 Both substances produced a significant increase of renin release 3 In the absence of calcium and magnesium, EDTA still increased rein release and there w...

Abstract We examined the efficacy of ethylenediaminetetraacetic acid (EDTA) for removing humic contaminants from collagen extracted ancient bone. Humic must be removed to obtain reliable stable isotope values bone collagen, given that acids have consistently lower δ 13 C than collagen. The purpose our research was examine if EDTA treatment could effectively remove and thus serve as an alternati...

The study was conducted to investigate the effects of ethylenediaminetetraacetic acid (EDTA) on seedling emergence, morphological characteristics, and photosynthetic pigments of Chenopodium album (L.) in lead (Pb) contaminated soil. The Pb contaminated soils were taken from Hirmand River. The soil samples mixed with 0.71 g Li-1 Pb (PbNO3)2 to increase the Pb concentration. EDTA was added to the...

OBJECTIVE The objective was to investigate the effect of intracanal antibiotic medicaments followed by ethylenediaminetetraacetic acid (EDTA) on the indentation properties and hardness of radicular dentin using a BioDent reference point indenter and a traditional microhardness technique, respectively. MATERIALS AND METHODS Specimens with intact root canal dentin surfaces and polished radicula...

The synthesis of ZnFe2O4 nanoparticles was performed using the solution combustion method with three types fuel, namely urea, glycine, and ethylenediamine tetra-acetic acid (EDTA) precursors (Zn(NO3)2.6H2O Fe(NO3)3.9H2O. process conducted in an open space at 300 °C for ± 1 h, resulting a brownish-black ZnFe2O4. Meanwhile, fuel type used affects physicochemical properties XRD analysis showed tha...
