The reagent used is a solution of o-dianisidine in aqueous acetone, which gives a red colour with [Fe(CN) b0] 3 when the pH 2.8 Beer's law is obeyed up to dilutions of 1:2.10 b6(D=10 b-6.3) and when 210-mm Nessler test-tubes are used, up to dilutions of 1:5.10 b6(D=10...
(or other solutions containing Fe3+), the product of the reaction is a solution with a blood red colour, due to the formation of the thiocyanatoiron complex ion. Thus this chemical is often used to create the effect of 'stigmata'. Because both solutions are colorless, they can be ...
It is challenging to completely remove colour pollutants from water using traditional wastewater treatment techniques such as absorption and o xidation8,9. In general, effluents containing soluble contaminants, solids, colloids, organic matter and minerals are removed through various physical, chemical...

is prolonged, and no visible change in spectral shape can be observed. Therefore, it is reasonable to ascribe this broadband emission to one Fe3+luminescence center. Considering the valence state and ion radius, it is speculated that the Fe3+ions occupy the octahedral In3+sites in CISO:Fe3...
Metal ion binding studies of 1 have been performed in CH3CN/H2O (3:1, v/v, 10 mM Tris-HCl buffer, pH = 6.90). Compound 1 senses multiple metal ions such as Al3+, Fe3+ and Fe2+ by exhibiting turn on fluorescence and colour change (colourless to pink) under different experimental ...

Enhanced photocatalysis of pristine g-C3N4 by modifying its surface with CeO2 and Fe3O4 can be explained firstly as the addition of CeO2 and Fe3O4 leads to modify the colour of this material, leading to the improved harvesting of visible light region as shown in UV-Vis DRS. Secondly, ...
(a) Atomic structure across the interface divided into six blocks labelled as (i–vi); colour coding as in Figs 2 and 3. (b) Spin-polarized partial density of states (SDOS) for the six structural blocks shown in (a). Fig. 4a. These structural regions represent complete formula ...
