چکیده
Iridium complex [(pq)(2)IrCl](2) (1) is established as a quantitatively operating lab-on-a-molecule in aqueous media at physiological pH. Acting as a chemodosimeter, 1 uses two channels, PL and ECL, for the detection of cyanide and acetate, with the former undergoing nucleophilic attack and the latter Kolbe electrolysis and radical-metal combination.

Synthesis of Copper Hydroxide Nitrate (Cu2(OH)3NO3) Micro-Sheets by Plasma Electrolysis of Cu(NO3)2 Aqueous Solution in Atmospheric Air
In the present paper, using a cathodic pin-to-solution electrical discharge electrolysis setup, interaction of the atmospheric air plasma with aqueous solution of copper nitrate and its possibility for synthesis of nano-materials is investigated. An AC (50 Hz) high-voltage power supply (5 kV) with rectified current is used for electrical discharge of the air between a metal pin and the solution...
متن کاملUranium Removal from Aqueous Solution Using Ion-Exchange Resin DOWEX® 2x8 in the Presence of Sulfate Anions
The current study was attributed to uranium (VI) ions adsorption using a anion exchanger resin, Dowex®2x8, in the presence of sulfate anions. Evaluation of operational parameters including contact time, pH, initial concentration of uranium ions, and presence of various anions (including phosphate, sulfate, chloride, fluoride, and nitrate) in the solution was assessed on sorption performance of ...
متن کاملAn iridium(III)-based lab-on-a-molecule for cysteine/homocysteine and tryptophan using triple-channel interrogation.
Iridium complex is a lab-on-a-molecule for recognising and quantifying cysteine/homocysteine and tryptophan in a mixture of all proteinogenic amino acids. UV-Vis and photoluminescence channels are suitable for quantification of homocysteine and cysteine in aqueous media, e.g. by emission enhancement at 606 nm, while tryptophan was selectively quantified in the electrochemiluminescence channel.

The removal of color from synthetic wastewater containing Congo red was experimentally investigated using electrocoagulation process. The effects of operational parameters such as current density, electrolysis time, electrolyte concentration, electrode distance, initial dye concentration, initial pH and temperature on color removal efficiency were investigated in this study. The tentative resul...
متن کاملComparison of Electrocoagulation and Chemical Coagulation Processes in Removing Reactive red 196 from Aqueous Solution
Background: Conventional chemical coagulation is considered as the old method to color and COD removal in textile effluent. Electrocoagulation (EC) process is a robust method to achieve maximum removal. Methods: This work was designed to compare the result of operational parameters including optimum pH and coagulant concentration for chemical coagulation with ferric chloride and alum. Also, th...
