Remazol Red

The color index (Cl) number, developed by the society of dyers and colorists, is used for dye classification. Once the chemical structure of a dye is known, a fivedigit Cl number is assigned to it. The first word is the dye classification and the second word is the hue or shade of the dye. For example, Cl Acid Yellow 36 (Cl 13065) is a yellow dye of the acid type. Additionally, a dye mixture may consist of several dyes for example, Navy 106 is composed of three reactive azo dyes remazol black B (Reactive Black 5), Remazol Red RB (Reactive Red 198), and Remazol Golden Yellow 3. 

The decolourization capacity of the white-rot fungus Phlebia tremellosa was investigated in detail. Dyes included in the experiments were Cibacron red, Remazol navy blue, Remazol red, Cibacron orange, Remazol golden yellow, Remazol blue, Remazol turquoise blue, and Remazol black B. The decomposition of Remazol black B was followed by RP-HPLC. Measurements were performed in an ODS column (250 X 4.6 mm i.d.) using ACN-water...

Quaternized cellulose is used as a sorbent to remove azo dyes from wastewater samples. For cellulose recycHng purposes reductive degradation was performed and products of Orange II and Remazol Red F3B were determined by ESI-LC-MS and MS spectra of azo dyes and reduction products were reported [429]. As major oxidative degradation products of the azo dye Uniblue A four reaction products were identified under UV irradiation (254 nm)/ peroxydisulfate treatment. Possible reaction pathways were discussed [421].

One of the first reports on yeast-mediated color removal by a putative process of biosorption of azo dyes by yeast (Rhodotorula sp.) biomass belongs to [31]. Yeast species such as Kluveromyces marxianus removed the diazo dye remazol black B [10], Candida catenulata and Candida kefyr removed more than 90% of amaranth by biosorption [6]. Biosorption uptake of the textile azo dyes remazol blue, reactive black, and reactive red by S. cerevisiae and C. tropicalis varied according to the selected dye, dye concentration, and exposure time [5, 7]. In a recent screening work carried out by [32], from the 44 yeast strains tested for their decolorization ability, 12 of them removed the dye Reactive Brilliant Red K-2BP by biosorption, among them the following were identified S. cerevisiae, Saccharomyces uvarum, Torulopsis Candida, and Saccharomycopsis lipolytica. 

Native Cassia angustifolia (CA) seed gum with 1 mL of PAC stock solution at highly acidic pH (pH = 2.5) has been shown to remove 35% Acid Sendula Red, 22% Direct Kahi Green, and 16% Reactive Remazol Brilliant Violet dyes [9] while at alkaline pH (pH = 10) under identical conditions, the decol-orization efficiency of CA is reported to be about 80%, 99%, and 45% for acid, direct and reactive dyes, respectively. CA acts as a good working substitute...
