Investigated physical properties of novel type four deep eutectic solvent.

Abstract

A deep eutectic solvent type four was created by combining 1:4 lithium chloride and 1,2 propanediol. The physical characteristics of pure DES and NiCl2.6H2O in DES with various additions such as H2O, Triton X100, Boric acid, and Nicotinic acid were examined. The results reveal that H2O and Triton X100 have a good improvement in increased conductivity and density, which is highly essential in electrodeposition applications. The UV-Vis spectra of 0.2 M NiCl2.6H2O solutions in DES in the presence and absence of additives were measured. In the absence of additives, we observed peaks at (402, 284, and 219) nm. When we added additives, we saw a blue shift. The results showed a blue shift when additives were added. Also the physical characteristics of CuCl2.2H2Oin DESs and with various additions such as Triton X100, Triton X114, Twien20 and Twien80. The results reveal that Twien80 and Triton X100 have a good improvement in increased conductivity and density, Too the UV-Vis spectra of 0.2 M CuCl2.2H2O solutions in DES in the presence and absence of additives were measured. Show that some of additives does not effect in UV-Vis spectrum such as twin 20 rather than other additives.
