o phenanthroline was discussed.The optimum conditions and the rate of the reaction were obtained,the detection limit for Ag + is 1.20×10 -6 g/L,the linear range of the determination is 0.01～0 20 mg/L for Ag +.The method was applied to determining the Ag + concentration in tap water...
An operationally simple domino approach for the silver-catalyzed synthesis of oxazine/benzoxazine-fused isoquinolines 5a-q and naphthyridines 6a-v by the reaction of o-alkynyl aldehydes 3a-aa with amines having embedded nucleophiles 4a-d under mild reaction condition in water is described. The reacti...
A versatile, cheaper, silver and water-free metathesis reaction was developed for imidazolium, phosphonium and pyrrolidinium based ionic liquids (ILs) associated with different anions such as dicyanamide, thiocyanate, tetrafluoroborate and bis(trifluoromethylsulfonyl) imide. This route, using the melt of ...
Reaction Mechanism of Oxygen Atoms with Cyanoacetylene in the Gas Phase and on Water Ice Reactions of atoms and molecules on dust grains coated by water ice have been considered to play an important role in the formation of many of the detected... HB Xie,YH Ding,Chia-chung Sun - 《Astrop...
During biosorbent regeneration, the adsorbent and eluent interact via electrostatic reactions, π–π bond reaction, hydrophobic reactions, and hydrogen bond reactions [73]. HNO3 is a proton exchange agent, which has been shown to be very efficient for metal cations desorption [73,74]. HNO3 was...

The reaction between K[Fe(CO)3(PPh3){Si(OMe)3}] and InX3(X = Cl or Br) gave complexes of the type Fe–In(-X)2In–Fe. The chloride-bridged complexes easily form adducts with two-electron donors such as pyridine or OPPh3. The structure of ... P Braunstein,M Knorr,M Strampfer...
This requires the elimination of the residual reducing agents solvents used for nanoparticle synthesis, as they are potentially capable of engaging in a reaction with H2O2. Ag0 NPs can also be synthesized by physical (thermal or UV-radiation) method which has many advantages as its low-cost, si...
Optimization of reaction parameters In order to obtain AgNPs of fine size and shape, optimization of the main reaction parameters was performed with contact time (5–45 min), silver salt precursor concentration (0.1–0.5%) and chitosan-algae extract proportion (4:1, 3:2, 2.5:2.5, 2:3, 1...
Human systemic effects by inhalation: skin effects. Inhalation of dusts can cause argyrosis. Questionable carcinogen with experimental tumorigenic data. Flammable in the form of dust when exposed to flame or by chemical reaction with C2H2, NH3, bromoazide, ClF3 ethyleneimine, H2O2, oxalic acid, H2...
