objective: evaluating the effect of dentin conditioning with edta on microleakage of composite resin restorations, using two etch and rinse and two self-etch adhesives. materials and methods: one hundred and sixty extracted molars received class v cavity preparations right under the cej and were randomly divided into eight groups of 20, usingfour different adhesive systems. these adhesives incl...

Festuca ovina L. is a hyperaccumulating plant which has aroused considerableinterest with respect to its possible use for phytoremediation of contaminated soils. Thisstudy has been conducted to evaluate the potentials of F. ovina L. to serve as aphytoremediation plant in the cleaning up of Cu in the polluted soils and to identifyextraction efficiency of Ethylene Diamine Tetraacetic Acid (EDTA) ...

the aim of this work was to study the ability of two biodegradable chelating agents, nitrilotriaceticacid (nta) and ethylenediiminopropanedioic acid (eddm) to complex metals, in the treatment of the pulp,prior to a totally chlorine free (tcf) bleaching process, and compare with the ethylenediaminetetraacetic acid(edta) performance. firstly, speciation efficiency index (sei) was calculated by co...

The objectives of this investigation are the studies on the effect of copper ion on photolytic degradation of ethylenediaminetertraaceticacid (EDTA), the effect of EDTA on electrolytic recovery of copper as well as the introduction of a novel combined photolytic and electrolytic cell system for simultaneous recovery of copper and the degradation of EDTA.In this experimental study, ...

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...
