background and purpose:organic dyes with a complex structure are often toxic, carcinogenic, mutagenic, non-biodegradation and stable in the environment and if released to the environment without treatment can endanger the environment and human health. the aim was to evaluate the performance nanoscalezero-valent iron (nzvi) in the removal of dye acid red 18 (ar18) from aqueous solutions. materia...

Colored effluents are one of the important environment pollution sources since they contain unused dye compounds which are toxic and less-biodegradable. In this work removal of Acid Red 14 and Acid Red 18 azo dyes was investigated by acidic treated pumice stone as an efficient adsorbent at various experimental conditions. Removal of dye increased with increase in contact time and initial dye co...

Acid Red 26 and 18 are two early synthetic dyes belonging to the monazo dye class. The molecular structure of this class is characterized by chromophoric azo group (NN) generally attached benzene or naphthalene derivatives containing electron withdrawing and/or donating groups as substituents. As both red have an OH in ortho- position respect group, they undergo azo-hydrazone tautomerism. In wo...

Three dye molecules (Dye) of Acid Brilliant Scarlet 3R (AR18), Amido Naphthol Red G (AR1), Indigo Carmine (IC), as well sodium dodecyl sulfate (SDS) dopant agents were used for electrochemical synthesis polypyrrole (PPy) layers onto indium doped tin oxide (ITO) coated polyethylene terephthalate (PET) electrode. The morphology, electrochemical, optical, and spectroelectrochemical properties the ...
