The use of Azolla filiculoides (AF) for the removal of Acid Red 88 dye (AR88) from aqueous solutions at different contact times, temperatures, pH, adsorbent doses and initial dye concentration was investigated. The extent of dye removal decreased with increasing adsorbent dosage and AR88 concentration, also increased with increasing contact time and temperature. The adsorption isotherms are des...

In recent years, combinatorial methods have attracted a great deal of attention. Among them, sono-combining techniques have shown a significant potential as an economic technology applicable and environment-friendly technology for wastewater treatment. In this study, Sono Electrochemical SE, Sono Photo Electrochemical SPE and Sono Photo Electro Catalytic SPEC techniques were investigated for de...

      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...

The present study deals with the decolorization of CI Acid Red SR (ARAN as a model contaminant from textileindustry using sawdust as an adsorbent. The effects of initial AR88 concentration, adsorbent dosage, pH. c not acttime and ',riming rah: wcrg studied in a batch mode. The variation of pH from 3 to 10 showed no considerablechange in decolorization rate. The desired conditions for decoloriza...

In this study, ZnO nanoparticles fixed on glass plates were employed as photocatalysts for the degradation of Acid Red 88 (AR88) dye in aquatic solution. ZnO nanoparticles were synthesized through coprecipitation method and fixed on glass plates. X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques were used for characterization of nanoparticle samples. A batch reactor equi...

The influence of the number of operating parameters on photocatalytic and sonocatalytic Acid Red 88 degradation from an aqueous solution was investigated in this paper. The experimental results indicated that the sonocatalytic process with Ni-TiO2 was far more effective for the degradation of high concentration azo dyes, regardless of the process condition. In order to achieve a larger surface ...
