Abstract
The removal of synthetic cationic dyes, methylene blue, from wastewaters by using Traganum Nudatum Roots, TNR, as low cost agriculture material, treated by Trona as novel activator. Parameters control the adsorption capacity of MB were studied. It was found that the maximum adsorption capacity was 339.16 mg MB/g TNR at pH 8.4 and increased with increasing solution pH. The adsorption capacities of MB dye increased with increasing concentration of MB and the maximum adsorption capacity was 292.09 mg MB/g TNR at initial MB concentration of 500mg/L. The MB dye was reached equilibrium within 90 min. The adsorption capacity decreased with increase in adsorbent dose for MB dye and the maximum adsorption capacity was 402.8 mg MB/g TNR at initial TNR dosage of 20 mg. The results indicated that the adsorption capacity increased for both dyes by rising the temperature from 303 K to 323 K, indicating that the adsorption process is an endothermic process and adsorption favorable at high temperature. The findings in this research that TNR treated with Trona as cheap and effective activator can be used to remove MB from aqueous solution and all the parameters studied had a significant effect on removal process.
