Applications of Ionic Liquids for the Development of ...

This paper reviews the primary literature reporting the use of ionic liquids (ILs) in optical sensing technologies. The optical chemical sensors that have been developed with the assistance of ILs are classified according to the type of resultant material. Key aspects of applying ILs in such sensors are revealed and discussed. They include using ILs as solvents for the synthesis of sensor ...

Electrochemical Detection of Ammonia Using a Thin Ionic ...

· This sensor, completed with a thin layer of ionic liquid [BMIM][NTf2] as the electrolyte, was successfully demonstrated as an NH3 sensor. It was shown that 1 ppm NH3 can be detected in ambient conditions (room temperature, 40% RH). The detection of NH3 was demonstrated both by amperometry and cyclic voltammetry. The detection based on cyclic voltammetry seems more feasible, because low concentrations could be clearly detected and sensor …

Detection methods of ammonia nitrogen in water: A review ...

· Similar to liquid-contact ion-selective electrodes, research into solid-contact ion-selective electrodes has mainly explored the performance of the sensing material. A copper-based and a silver-based ammonium ion selective electrode has been applied to aquaculture water, however the detection concentration is not low (copper and silver linear range of 10 μM‒10 mM and mM–100 mM ...

Ionic liquid - Wikipedia

An ionic liquid (IL) is a salt in the liquid state. In some contexts, the term has been restricted to salts whose melting point is below some arbitrary temperature, such as 100 °C (212 °F). While ordinary liquids such as water and gasoline are predominantly made of electrically neutral molecules, ionic liquids are largely made of substances are variously called liquid electrolytes ...

Ultrasensitive gaseous NH3 sensor based on ionic liquid ...

· This work reports that ammonia (NH(3)) can be used as an efficient co-reactant for tris(2,2'-bipyridine)ruthenium(II) (Ru(bpy)(3)(2+)) electrochemiluminescence (ECL) in ionic liquids (ILs), on the basis of which a signal-on ECL sensor for directly detecting gaseous NH(3) has been developed. The NH(3) ECL sensor has a very high sensitivity, with a detection limit of 10 ppt NH(3) (at signal-to-noise …

Applications of Ionic Liquids in Electrochemical Sensors ...

Ionic liquids (ILs) are salt that exist in the liquid phase at and around 298 K and are comprised of a bulky, asymmetric organic cation and the anion usually inorganic ion but some ILs also with organic anion. ILs have attracted much attention as a replacement for traditional organic solvents as they possess many attractive properties. Among these properties, intrinsic ion conductivity ...

Li(NH3)B3H8: a new ionic liquid octahydrotriborate ...

· We report a strategy of using small cations to construct ionic liquid octahydrotriborate. The novel liquid Li(NH 3)B 3 H 8, prepared by a facile reaction of NH 4 B 3 H 8 with LiH, froze below − °C and crystallized into a monoclinic unit cell with lattice parameters of a = (1) Å, b = (1) Å, c = (1) Å, and β = (5)°, providing a promising functional liquid ...

Ammonia probe - Sensors - Arduino Forum

· These ISE (Ion Selective Electrode) are available for a growing number of common anions and cations of interest. It's basically an electrochemical cell with some sort of membrane that can only pass the analyte of interest. Works like a pH probe and if you know how to do the math to calibrate it you can read one with any pH meter. They do tend to be quite expensive though, an ISE for ammonia ...
