2000. Why do Congo Red, Evans Blue, and Trypan Blue Differ in Their Complexation Properties? Journal of Computational Chemistry 21: 656–667.Skowronek M, Roterman I, Konieczny L, Stopa B, Rybarska J, Piekarska B. (2000) Why do Congo red, Evans blue and Trypan blue differ in their ...
Chemical properties Congo red is red-brown powder, soluble in hot water and the cold water 10 times of its weight; the color of the solution is yellow-red; soluble in ethanol and the solution is orange; slightly soluble in acetone, while almost insoluble in ether. The solution is dark blu...
Preparation of Graphene Oxide-XFe2o4 (X = Co, Mn, Ni) Nanocomposites and their Application in Adsorption Organic Dye from Aqueous Solution The present study compared the properties of XFe2O4/GO formed from the magnetic metal sites including Co, Mn and Ni using the polymerized complex method....
The effect of pine bark dosage, which was varied from 1 to 10 g L−1, on CR adsorption was studied at 25 °C with a Congo red solution of 5 mg L−1 at the two pHs leading to the highest dye removal, 2 and natural pH. The kinetic behaviour was also well represente...
Physicochemical properties: Red note. It is obtained by immersing the filter paper in the prepared Congo red solution, impregnating, drying and cutting, and attaching the standard color scale for comparison. Blue in case of inorganic acid

Congo RedPH SensorThe fabrication of nano porous silicon, nPSi, using alkali etching process has been studied and carried out. The surface chemistry of anisotropic etching of n-type Si-wafer is reviewed and the anisotropic chemical etching of silicon in alkaline solution using wetting agents is ...
Direct Red 28 Properties and Applications: Soluble in water for yellow light red solution, soluble in ethanol for orange, soluble in acetone. In the strong sulfuric acid as dark blue, diluted into shallow blue, blue precipitation. Dyes to acetic acid solution for blue purple, have red...
The present work aims at embedding CuO in silicate (CuO.SiO2) and aluminosilicate (CuO.NaAlSiO8) composites to reduce both Cu(II) leaching and adsorption of anionic dyes such as Congo red (CR) which is thought to give more opportunity for the reaction of H2O2 with the surface. CuO.SiO2 ...
