In this study, we used advanced oxidation process (AOP)for the removal of a cationic and anionic blue dyes, namely Basic Blue 3 (BB3) and Acid blue 62(AB62), from aqueous solutions. Fenton reactions are mixture of H2 O2 and Fe2+. However this paper investigates the application of twelve different catalysts such as: FeCl2 , FeSO4, (NH4 )Fe(SO4 )2 , FeCl3 , Nano iron (Fe0 ), Fe(NO3 )3 , K2FeO4 , ...

Currently, biological method has been utilized in the treatment of wastewater -containing synthetic dyes used by textile industries in Iraq. The present work was devoted to study the operating feasibility using reverse osmosis (RO) and nanofiltration (NF) membrane systems as an alternative treatment method of wastewater discharged from Iraqi textile mills. Acid red, reactive black and reactive ...

of cancer with the hope of developing useful diag nostic and therapeutics agents. The aim in such investigations has been to find a dye which, in the intact animal, stains living tumor cells without staining surrounding tissue. A large number of acid dyes, especially in the azo series, has been rather intensively investigated for such a purpose. From these investigations there has resulted gen ...

Tartaric acid modified wheat bran was utilized as adsorbent to remove methyl blue, a basic dye from aqueous solution. Batch experiments were carried out to study the effect of various experimental parameters such as initial solution pH, contact time, initial dye concentration and adsorbent dosage, on dye adsorption. The results showed that the modification of wheat bran by tartaric acid signifi...

A synthesized functionalized pillared porous phosphate heterostructure (PPH), surface functionalized phenyl group, has been used to remove the dye Acid Blue 113 from wastewater. X-ray photoemission spectroscopy XPS and X-ray diffraction (XRD) were used to study its structure. The specific surface area of this was 498 m²/g. The adsorption capacities of PPH and phenyl surface functionalized (Φ-PP...

Bioaccumulation of synthetic dyes viz. Acid Blue 93, Direct Red 28 and Basic Violet 3 by the environmental yeast isolate, Candida tropicalis growing in aqueous extract of sugarcane bagasse medium was studied in a batch system as a function of initial pH and dye concentrations. The optimum pH value for bioaccumulation was found to be 3.0 for Acid Blue 93 and Direct Red 28 and 5.0 for Basic Viole...

Ten phenols were selected as natural laccase mediators after screening 44 different compounds with a recalcitrant dye (Reactive Black 5) as a substrate. Their performances were evaluated at different mediator/dye ratios and incubation times (up to 6 h) by the use of Pycnoporus cinnabarinus and Trametes villosa laccases and were compared with those of eight known synthetic mediators (including -...

synthetic dyes are among the most common contaminants of the environment. therefore, the aim of this study was investigation the removal of basic blue 41 (bb41) and methylene blue (mb) from industrial effluents by useing raw and modified rice stems. in this study raw and modified rice stems treated chemically with citric acid (ca) and were used to explore the potentiality of rice stems for remo...
