BackgroundandObjectives: Dyes are organic compoundswith complex structures,which due to toxicity, carcinogenicity and nonbiodegredabity, this type of pollutants is one of the most important pollutants of the environment. The goal of this researchwas to study the feasibility of the application of solar irradiation in presence of potassium persulfate (K2S2O8) for the removal of Reactive blue19 (R...
Methyl red, a synthetic azo dye, was reported for not only being mutagenic but also its persistence has severe consequences on human health, such as cancer, alongside detrimental environmental effects. In the present study, Pseudomonas putida OsEnB_HZB_G20 strain isolated from soil sample to study catalytic activity degradation of methyl red dye. Another strain, aeruginosa PA 1_NCHU used an ele...
In the present world scenario, environmental problem is a very serious due to industrialization and urbanization development results in air, water soil pollutions. Water main consuming sources many of industries waste industrial effluents discharge into environment. Their impacts are directly indirectly affect our living organism vegetation. The review paper describes about dyes removal using l...
The high demand for dyes in the paper, cosmetic, clothing, leather, and food industries drives up use of as a result industrialization. As result, wastewater production from dye manufacturing activities will rise. presence their structural compounds industrial sources place humans, animals plants lives at risk. Synthetic are more challenging to decolorize because they resistant chemical physica...
Dyes are synthetic organic compounds widely used in various industries such as, textile, leather, plastic, food, pharmaceutical, and paints manufacturing industries. Coloured effluents are highly toxic to the aquatic life and mutagenic to humans. Wastewater containing dyes has become an important issue demanding serious attention. Among the synthetic dyes, azo dyes are the largest and most wide...
Introduction The application and increasingly produce of colorants, particularly, synthetic dyes, are one of the main environmental and health concerns especially in industrialized countries. If this type of dyes is discharged into the environment without any control, many problems will arise. Therefore, it is necessary to remove the dyes from aqueous solutions using appropriate methods. The p...
Introduction: Today, contamination of surface and underground water sources with textile dyes is one of the most serious environmental problems facing humans. Nanocomposites are a new generation of superabsorbents that have been proposed by many researchers as a promising strategy to reduce water pollution. In this study, a ceramic carbon nanocomposite containing multi-wall carbon nanotubes was...
The present study focuses on effects of operational parameters on electrochemical wastewater treatment for synthetic wastewater. Electro-oxidation has emerged as one of the advanced oxidation processes gaining more attention because it offers many distinctive advantages over other conventional methods such as versatility, high treatment efficiency, safety, amenability of automation and cost eff...
A general method for the immobilization of DNA through its 5'-end has been developed. A synthetic oligonucleotide, modified at its 5'-end with an aldehyde or carboxylic acid, was attached to latex microspheres containing hydrazide residues. Using T4 polynucleotide ligase and an oligonucleotide splint, a single stranded 98mer was efficiently joined to the immobilized synthetic fragment. After im...
