NOVEL REACTIVE RED DYES - autexrj.com
Dye manufacturers have for a long time recognised the need to improve the fixation levels of reactive dyes. As a result some of the reactive dyes with more than one reactive group in the dye molecule have been investigated. Reactive systems are often classified according to the number of reactive groups contained in the dye molecule, as mono ...

The presence of reactive dyes increases the value of the PZC by enhancing the ability of sawdust for protons uptake. This is due to basic sites (basic nitrogen atoms) present in the dyes molecules. The variation of the PZC also confirms the effective immobilization of reactive dyes onto Ayous sawdust. 3.2. Pb(II) adsorption3.2.1.

The removal of Acid Red 183 (AR183) and Reactive Blue 4 (RB4) from single and binary solutions onto a waste material (WM) from the boron industry was studied. The adsorption capacities of AR183 and RB4 on WM in single dye solutions were found to be 9.11·10−5 mol·g−1 and 7.33·10−5 mol·g−1, respectively. Because of competitive adsorption, the adsorption capacities in binary solutions ...
Artist Grade Oil Colors - Gamblin Artists Colors
Red lead, which definitely blackens in air, was used as a substitute for genuine Vermillion because it was a less expensive pigment. By the 1930's, lightfast, permanent with considerably lower toxicity, Cadmium Red had replaced Vermillion on artists' palettes. The red earths are common in mural painting and easel painting throughout history.
