Application of Acaciatortilis Shuck as of Low-cost Adsorbent to Removal of Azo Dyes Reactive Red 198 and Blue 19 from Aqueous Solution
Authors
Abstract:
Background & Aims of the Study: Textile wastewaters are very various in chemical qualities. In other words, these industries are one of the largest producing dyes compounds; therefore their treatment is so complex and difficult. The aim of this study was to evaluate the potential removal of Reactive Red 198 and Blue Reactive 19 from synthetic solution by Acaciatortilis shuck as a naturally absorbent . Materials & Methods: The dyes samples with concentration (10, 50 and 500 mg/L) was prepared in laboratory. Next step was to determination of optimum pH among (pH solutions of 2, 4, 6, 8 and 10) and optimum adsorbate dosage with mesh 30-60 and 60-100 among (0.5, 1, 2, 3 and 4 g/L).Sampling in times 10, 20, 40 and 80 minute was done from the supernatant and was filtered (through 0.45 µm); finally the dye concentration was obtained by Spectrophotometer device. Adsorption isotherms of dyes Acaciatortilis shuck can were determined and correlated with common isotherm equations such as Langmuir and Freundlich models. Results: The highest efficiency of dye removal from dyes solutions in pH 4, 10 min contact time and 2 g/L adsorbate dosage and using mesh 60-100 was for both Reactive Red 198 and Blue 19. Also the adsorption rate of reactive dyes was increased by increasing of initial dye concentration. The efficiencies for Reactive Red 198 and Blue 19 were 77.54% and 77% respectively. Adsorption isotherms was examined by Freundlich and Langmuir isotherm that finally showed the Freundlich multe-layer isotherm has better accordance with dates. Conclusions: The results illustrate Acaciatortilis shuck is effective adsorbent and can be used as an available and inexpensive adsorbent to removal of textile dyes from effluent.

The removal ofxylenol orange from aqueous solution onto the coal ash was investigated at room temperature. The results show that the adsorption capacity of xylenol orange increased as the adsorption time increased and then equilibrium established after 30 min adsorption time. The results obtained revealed that the coal ash removed about 80 % of xylenol orange from the aqueous solution withi...
