The method is based on the enhancement of the colour intensity of the Fe(III)-SCN complex due to the addition of the drug imipramine. The value of molar absorptivity of the Fe(III)-SCN imipramine complex in terms of the drug lies in the range of (2.77–3.16) × 103 L/mol cm at ...
To extract Ni(II), many researchers used ionic liquids such as Cyphos IL 101 and Task-Specific Ionic Liquids (TSILs) with thiocyanate (SCN−), as well as Primene JMT-Cyanex 272 ionic liquid (Wellens et al., 2013; Boudesocque et al., 2020; Coll et al., 2012). The bi-functional...
When Fe3+ ions concentration was increased from 2 to 10 μM, fluorescence colour of IRMOF-3 changed from light blue to dark blue. This is also observed by naked eyes. This shows that the prepared IRMOF-3 can be used for visual detection of Fe3+ ions as shown in Fig. 4(b). 3.9...
