INTERACTION BETWEEN BASIC DYES AND 2-NAPHTHALENE SULFONIC ACID SODIUM SALT IN AQUEOUS SOLUTIONS

Use of Fenton Reagent as Advanced Oxidative Process for Removal of Basic and Acid Red Dyes from Aqueous Solutions

In this study, the Fenton process was used to investigate the color removal efficiency of Acid Red 52 and Basic Red 18 dye solutions by direct chemical oxidation. Color and chemical oxygen demand (COD) was successfully removed more than 99% and up to 92% respectively. This article would provide an easy assessment of the viability of using Fenton reagent in acidic conditions, so it is a prom...

Photocatalytic Degradation of Anionic Azo Dyes Acid Orange 7 and Acid Red 88 in Aqueous Solutions Using TiO2-containing Hydrogel

      The photocatalytic degradation of two anionic azo dyes Acid Red88 (AR 88) and Acid Orange 7 (AO7) was investigated in aqueous solution using a TiO2-containing hydrogel and UV light. The pH-sensitive hydrogel poly (styrene-alt-maleic anhydride) (PSMA), was synthesized and crosslinked in the presence of melamine and TiO2 nanoparticles which results in entrapment of TiO...

Preparation and Characterization of Nano-lignin Biomaterial to Remove Basic Red 2 dye from aqueous solutions

The present study prepares alkali lignin (AL) via acidification of black liquor, obtained from a pulp and paper factory. The average molecular weight of AL (equal to 2,530 g/mol) has been determined with gel permeation chromatography. AL has been modified by ethylene glycol, while lignin nanoparticles (LN) has been prepared through acid precipitation technology, their size being assessed by mea...
