Coloring substances in food are generally classified into two categories, namely natural dyes and synthetic dyes. Rhodamine B is a dye which widely used the textile industry. The use of can cause irritation to digestion, inhalation, eyes. This research was conducted detect rhodamine content tomato sauce by adding detergent. design this study qualitative descriptive on market. test results for p...

The synthetic food dyes studied were rose bengal (RB), phroxine (PL), amaranth, erythrosine B (ET), allura red, new coccine, acid red (AR), tartrazine, sunset yellow FCF, brilliant blue FCF, and indigo carmine. First, data confirmed that these dyes were not substrates for CYP2A6, UGT1A6, and UGT2B7. ET inhibited UGT1A6 (glucuronidation of p-nitrophenol) and UGT2B7 (glucuronidation of androstero...

Introduction: Dyes are visible materials and are considered as one of the hazardous components that make up industrial waste. Therefore it is removed from bodies of water, using various methods. In this regard, the Fenton oxidation process is one of the most effective ways to remove colored contaminants in aquatic environments, which has many applications today. Materials and Methods: In this...

releasing of textile dye effluents into general water bodies is a major environmental and healthproblem. color removal, in particular, has recently become of major scientific interest, as indicated by themultitude of related research reports. during the past two decades, several physico-chemical decolorizationtechniques have been reported, few, however, have been accepted by the textile industr...

In this paper, dye removal ability of the surface modified nanoparticle SMN copper ferrite from single and quaternary systems was investigated. Acid Blue 92 AB92, Direct Green 6 DG6, Direct Red 23 DR23 and Direct Red 80 DR80 were used as model compounds. The effect of surfactant concentration, adsorbent dosage, dye concentration and pH on dye removal was evaluated. The adsorption isotherm and k...

Due to the awareness of impact synthetic dye on human health and environment, natural lake pigment have attracted considerable attention from researcher. Herein, pink−red sappanwood was prepared using adsorption approach. The effects initial pH, pH concentration brazilein solution, dosage aluminium hydroxide, time were also explored. Results showed that maximum capacity 30 mg g-1 achieved when ...

Introduction: Dyes have complicated structures, they are usually toxic and resistant to biological treatment and enter the environment through industrial waste streams. The aim of this study was to review the isotherm and kinetic adsorption studies of Reactive Blue 19 (RB19) dye onto Jujube stems powder from synthetic textile wastewater. Materials and Methods: This study was conducted in labo...

Background & Aims of the Study: Azo dyes are used in industrial processes such as textile industry to produce large quantities of colored effluents that contain organic and non-organic materials. So, effective and efficient treatment of them is important for the environmental protection. The aim of this study was to evaluate the efficiency of powder and granular pumice for the ...
