EDTA and its salts have a number of applications in medicine and pharmacy. EDTA is used to remove calcium from the human body, and serves as an anticoagulant and as a detoxicant after poisoning by heavy metals. It is often used in analytical chemistry for complexometric titrations and many other...
Experimental investigations and field applications showed noticeable increase in the oil recovery when low salinity water flooding is used. The mechanisms leading to the increase in oil recovery by low salinity water injection are debatable. Furthermore, low salinity water injection requires rel...
EDTA-based remediation is reaching maturity but little information is available on the state of chelant in remediated soil. EDTA soil retention was examined after extracting 20 soil samples from Pb contaminated areas in Slovenia, Austria, Czech Republic and USA with 120 mM kg−1 Na2H2EDTA, CaNa2E...
A novel process for the recovery of manganese by EDTA/EDTA–2Na leaching and the recovery of silver by thiosulfate leaching with resultant EDTA–Mn as the catalyst from manganese–silver ores was developed in this study. Initially, insoluble manganese(IV) was reductively leached by EDTA/EDTA–2N...
A droplet-based microfluidic synthesis approach for preparation of ficin capped gold nano clusters (AuNCs) was developed. Well dispersed AuNCs could be procured within 8 min. Upon excitation wavelength at 340 nm, the resultant AuNCs exhibited a strong blue fluorescence with the maximum emission ...
Chemical immobilization of arsenic (As) in contaminated sites may be achieved through the use of inorganic and organic soil amendments to reduce its bioavailability. The chemical immobilization of As-rich soil by using ethylenediaminetetraacetic acid ferric sodium salt (EDTA-Fe) and calcium pero...
A cheap sodium ferric EDTA-derived material (EDTAFeNa-KB-HT1) was prepared via one-step pyrolysis of a complex of Ketjenblack EC-300J and inorganic-organic hybrid EDTAFeNa, which was employed as both nitrogen and ferric precursors. The EDTAFeNa-KB-HT1 was proved to be an iron and nitrogen co-dop...
C/Fe3O4 hybrid materials have potential applications in sensors and anode materials for lithium-ion batteries. In this text, a one-step pyrolysis method was used to prepare C/Fe3O4 hybrid materials from EDTA ferric sodium salt. The magnetic Fe3O4 nanoparticles can be homogeneously incorporated i...
We present a facile one-step approach to large-scale production of single-crystal magnetite Fe3O4 nanosheets (NSs) employing a solid-state thermal decomposition route without the assistance of any template, carrier gas, and other additions. Single-crystal Fe3O4 NSs with average edge length in th...
A series of spirocyclic compounds inspired by Eli Lilly's phase 1 antidiabetic FFA1 receptor agonist LY2881835 was designed to include polar aromatic periphery groups and explore a possibility of building additional contacts with the target near the agonist binding site. The frontrunner com...
Glucokinase activators represent a promising potential treatment for patients with Type 2 diabetes. Herein, we report the identification and optimization of a series of novel indazole and pyrazolopyridine based activators leading to the identification of 4-(6-(azetidine-1-carbonyl)-5-fluoropyrid...
Three new silver(I) coordination compounds based on 2-ethyl-3-methylpyrazine (epyz), [Ag2(epyz)(pta] (1), [Ag4(epyz)2(ipa)2] (2) and [Ag8(epyz)4(npa)4] (3, H2pta = o-phthalic acid, H2ipa = m-phthalic acid, H2npa = 1,4-napthalenedicarboxylic acid), have been synthesized and have been characterize...
The recovery of manganese metal from manganese carbonate precipitate by leaching–purification–electrowinning was studied. The manganese carbonate precipitate from Baja Mining Corp.'s El Boleo project was readily leached into acidic ammonium sulfate solution. The manganese extraction reach...
79Se is among the most important long lived radionuclides in spent nuclear fuel and selenite, SeO32−, is its typical form in intermediate redox potential. The sorption behaviour of selenite and the bacterial impact on the selenite sorption in a 7-m-deep profile of a nutrient-poor boreal bog was ...
Electrolytic manganese metal has been used in a wide range of applications such as production of steel and aluminum alloys. However, manganese electrowinning is technically and commercially challenging due to a low current efficiency and high cell voltage. Rigorous purification and the use of ad...
Selenite adsorption on water-washed manganese nodule leached residues (WMNLR) was studied with the aim of detoxifying industrial effluents before their safe disposal into the environment. WMNLR, a solid waste material, was characterized with the help of XRD, FTIR, TG-DTA, pHpzc, BET surface area...
The accumulation of organic selenium (Se) in grains is helpful in understanding its bioaccessibility in various Se-enriched rice cultivars after soil selenite treatments. In the present study conducted with two rice cultivars, the organic Se as well as the glutelin-derived Se and the selenomethi...
This study was carried out to investigate the adsorption characteristics of leached manganese nodule residue (MNR), generated from the reduction roasting–ammonia leaching process, towards aqueous selenite. Physicochemical characterization revealed that the leached residue was a complex mixture ...
Denitrifying anaerobic methane oxidation (DAMO) is the process of coupling the anaerobic oxidation of methane (AOM) with denitrification, which plays an important part in controlling the flow of methane in anoxic niches. In this study, we explored the feasibility of microbial selenite reduction ...
Inorganic arsenic is the most toxic form and has been classified in group 1 as carcinogenic to humans which induces lung, urinary bladder and primary skin cancer. Worldwide concern over its presence in water bodies have prompted much research and policy development focusing on the removal of thi...
