1. Insoluble salts of alklaine earth metals (e. g. calcium phosphate) dissolve in non-aqueous solvents containing EDTA salts of organic cations (e.g. tetraethylammonium). 2. Bone is efficiently demineralized in ethanolic trimethylammonium EDTA. Retention in the matrix of water-soluble materials (e.g. proteoglycan) is much better than in standard aqueous EDTA demineralization procedures.

[C]ethylenediaminetetraacetate (EDTA) was shown to be slowly biodegraded to CO(2) in soils and sediments under aerobic conditions and by microorganisms in mixed liquid culture. EDTA chelates of Cu, Cd, Zn, Mn, Ca, and Fe added to soil were equally degraded, while Ni-EDTA was degraded more slowly.

OBJECTIVE The objective of the study was to evaluate the effectiveness of chitosan and chitosan-ethylenediamine tetraacetic acid (EDTA) (3:1,1:1,1:3) in comparison with 5.2% sodium hypochlorite (NaOCl) in disinfecting Enterococcus faecalis biofilm on root canal dentin and in the removal of smear layer with minimal erosion. MATERIALS AND METHODS Seventy single-rooted extracted human mandibular...

The interaction of EDTA with calcium silicate hydrate (C-S-H) and its impact on the sorption U(VI) by C-S-H in presence at varying concentrations has been investigated under N2 ambient atmosphere. solid phase characterization was performed FTIR, XRD TGA measurements uranium concentration solution determined alpha-spectroscopy. At increased ([EDTA] > 0.1 M) is complexed extensively extracted ...

The influence of ethylenediaminetetraacetic acid (EDTA) electrolyte additive on the performance Zn?air batteries with near-neutral chloride-based electrolytes was examined for primary and secondary batteries. electrochemical measurements indicated that Zn is not completely active in neat 2 M NaCl, but still could be discharged up to 1 mA cm?2 around ?1.0 VAg/AgCl. characterization surfaces reve...

The detection of protein lysine acylations remains a challenge due to lack of specific antibodies for acylations with various chain lengths. This problem can be addressed by metabolic labeling techniques using carboxylates with reactive functionalities. Subsequent chemoselective reactions with a complementary moiety connected to a detection tag enable the visualization and quantification of the...

This study evaluated the effect of EDTA and lysozyme on the antibacterial activities of activated ovotransferrin against 5 strains of Listeria monocytogenes. First, a disc test was performed to screen the concentrations of EDTA or lysozyme that showed antibacterial activities in ovotransferrin (O) or ovotransferrin in 100 mM NaHCO3 (OS) solution. Turbidity and viability tests were conducted usi...

We tested the hypothesis that controlled deficit irrigation (CDI) of the fast growing, salinity resistant Eucalyptus camaldulensis tree with timely EDTA application can enhance sediment clean-up while minimizing leaching of metal complexes. 220-L lysimeters containing a sand-metal-polluted sludge mixture. Established saplings were irrigated with tap or desalinized (RO) water with/without 4-time...
