Adsorption of aqueous Cd2+, Pb2+, Cu2+ ions by nano-hydroxyapatite: Single- and multi-metal competitive adsorption study
nano-hydroxyapatite (nano-HAP) Cd Pb Cu competitive adsorption selectivity coefficients
2017/8/9
Being an inexpensive but efficient adsorbent, hydroxyapatite is extensively used for decontaminating wastewater and soils polluted by heavy metals. However, its solubility and grain size can affect it...
Detection of ions released from S-PRG fillers and their modulation effect
Giomer Ion release pH
2010/11/29
The purpose of this study was to analyze the ions released from a surface pre-reacted glass ionomer (S-PRG) filler in distilled water or lactic acid solution. S-PRG filler was mixed with either soluti...
Spectrofluorimetric Determination of Famotidine in Pharmaceutical Preparations and Biological Fluids through Ternary Complex Formation with Some Lanthanide Ions: Application to Stability Studies
spectrofluorimetry lanthanide ions famotidine
2009/10/30
A simple, sensitive and specific method was developed for the determination of famotidine (FMT) in pharmaceutical preparations and biological fluids. The proposed method is based on ternary complex fo...
Effects of age and magnesium ions on oxygen toxicity in the neonate chicken
hyperbaric age magnesium ions oxygen toxicity animal chicken
2009/7/20
White Leghorn male chicks, 2-6 days and 4 weeks old, were injected with MgCl2 (2 mM Mg/kg body weight) and exposed to 100% O2 at 75 lb/in2 (approximately 5 atm). Compared to saline-injected controls, ...
