The purpose of this paper is to determine the amount of water in ionic liquid aqueous solutions that does not form hydrogen bonds (that is to say, free water). Here, the amount of free water was determined in mixtures of water and four ionic liquids

This paper discusses the development and implementation of a method based on NIR spectroscopy for the in-situ determination of the ammonia mass fraction of ammonia/water mixtures in an absorber test bench. The calibration model was established using

We used near infrared spectroscopy (NIR) and nuclear magnetic resonance, 1H NMR and 19F NMR to analyze the structural changes of 1-(2-hydroxyethyl)-3-methylimidazolium tetra fluoroborate ionic liquid (IL) when it interacted with ammonia. The NIR spec

We rank the expected solubilities of ammonia in three hydroxyl ionic liquids – [HOEMIm][BF4], [HOEMIm][NTf2] and [Ch][NTf2] – in the temperature range 20–105 °C by analyzing the cations and anions available for interaction with ammonia. As thi

The photodegradation process of three azo-dyes - Acid Orange 61, Acid Red 97 and Acid Brown 425 - was monitored simultaneously by ultraviolet-visible spectroscopy with diode array detector (UV-vis-DAD) and (1)H-nuclear magnetic resonance ((1)H-NMR).
