As in the natural madder lake aluminum hydrate (alum) is used as a substrate for the synthetic variety, most commonly known as alizarin crimson. The classical forerunner of metallizable anthraquinone dyes was alizarin, which produced the aluminum complex dye Turkey Red by the mordanting process (Scheme 1). Its aluminum lake, carmine, is soluble in alkaline media and has higher stability to heat, light and oxygen. The synthesized material was characterized in detail, while the adsorption of the dyes was monitored by UV-Vis spectroscopy. This effect can be explained if we note that the cationic character of the coagulant may be reduced as the medium becomes more alkaline. Part of alizarin can be extracted directly from the root of three-year-old plants while the higher yield of colorants especially purpurin could be obtained from the plants after two years’ storage. They reds that were extracted were so renowned that even now we use the same names to describe these shades. Roy C. Ellis. Alizarin and purpurin have antimicrobial and antifungal activity against different pathogenic bacteria (Bechtold and Mussak, 2009; Chenciner, 2000). The adsorption process reached equilibrium within 90 min, and the removal efficiency increased with the enhancement of initial dye concentration, adsorbent dosage, and contact time, but decreased with the enhancement of solution pH.
