Computer simulation on a continuous moving chelation boundary in ethylenediaminetetraacetic acid-based sample sweeping in capillary electrophoresis

Journal of Chromatography A, 2009
This paper introduces a mathematic mode of moving chelation boundary (MCB) for computer simulation of a continuous EDTA-based sample sweeping in capillary electrophoresis (CE). Besides the equations of MCB used herein, the mode also includes electro-neutrality equation, constant current density, jump boundary condition of MCB, Kohlrausch' regulating ...

Direct and Continuous Measurement of Phospholipase D Activities Using the Chelation-Enhanced Fluorescence Property of 8-Hydroxyquinoline

, 2018
Phospholipase D (PLD) hydrolyzes phospholipids to form phosphatidic acid (PA) and the corresponding headgroup. To date, PLD has been linked to several pathologies, such as cancer, making this enzyme an important therapeutic target. However, most PLD assays developed so far are either discontinuous or based on the indirect determination of choline ...

A novel isotachophoresis of cobalt and copper complexes by metal ion substitution reaction in a continuous moving chelation boundary

The Analyst, 2009
A novel separation mode of isotachophoresis (ITP) was advanced for the study on the continuous moving chelation boundary (MCB) formed with EDTA and two metal ions of Co(II) and Cu(II). The experiments were performed systemically. The relevant results indicated that: (1) there were three boundaries in the whole system, viz., a sharp MCB, a wide moving ...

Exploring the Influence of Chelating Agents on Particle Formation in Continuous Coprecipitation

ECS Meeting Abstracts
This talk discusses the role of chelating agents in influencing the electrochemical performance of transition metal hydroxide-based cathode materials for energy storage applications. The focus is placed on how variations in the molar ratios of different chelating agents during ammonia-free continuous coprecipitation processes affect particle formation,

Recovery of Cu(II) from nickel laterite leach using prereduction and chelating resin extraction: Batch and continuous experiments

The Canadian Journal of Chemical Engineering, 2018
AbstractThe processing of laterite ores for nickel and cobalt production is increasing to meet the global demand for these metals. Sulphuric acid is used as a leaching agent, and metals present in the solution may be recovered by many different processes, such as ion exchange.

A Case of SAA with Secondary Hemochromatosis: Can Continuous Iron Chelation Reverse Both Bone Marrow and Multiple Organ Failures?.

Blood, 2006
Abstract A 24-year-old male patient with hemochromatosis due to multiple packed red blood cell transfusions, was referred to our emergeny center for a treatment of severe aplastic anemia and dyspnea. He was diagnosed with aplastic anemia at the age of 11 and had developed a transfusional hemochromatosis after 5 years of multiple blood ...

Effect of continuous vs sequential chelation on the mechanical properties of root dentin: An ex vivo study

Journal of Dentistry
To evaluate the mechanical properties of root canal dentin treated with sodium hypochlorite (NaOCl) in combination with hydroxyethylidene diphosphonic acid (HEDP) or ethylenediaminetetraacetic acid (EDTA).For testing fracture resistance, 45 single-rooted teeth were instrumented and irrigated with NaOCl/HEDP, NaOCl/EDTA, or distilled water.

Removal of trace metals by continuous ambulatory peritoneal dialysis after desferrioxamine B chelation therapy.

Clinical nephrology, 1991
We studied the removal of aluminum (Al), iron (Fe), copper (Cu), lead (Pb) and zinc (Zn) with continuous ambulatory peritoneal dialysis, before and after desferrioxamine B (DFO) administration (2 g intravenously) in two patients with chronic renal failure and Al-related osteopathy.

[Continuous remediation of heavy metal contaminated soil by co-cropping system enhanced with chelator].

Huan jing ke xue= Huanjing kexue, 2015
In order to elucidate the continuous effectiveness of co-cropping system coupling with chelator enhancement in remediating heavy metal contaminated soils and its environmental risk towards underground water, soil lysimeter (0.9 m x 0.9 m x 0.9 m) experiments were conducted using a paddy soil affected by Pb and Zn mining in Lechang district of Guangdong
