Abstract

         Benzene is one of the biggest challenges of groundwater pollution due to of its toxicity, motility in the environment, and solubility in groundwater. Granular dead activated sludge (GDAS) was investigated as low-cost, and locally available as a sorbent material for removing benzene from aqueous solution. The experimental results show that the removal efficiency has improved, with increasing both of GDAS amount and the time of contact and decreasing the initial concentration of the contaminant. Batch investigations demonstrated that the GDAS efficiency removal for benzene is ranged from 55%-76% while, the maximum uptake (qm) is 14.835 mg/g, at sorbent dose 5 g/100 mL and contact time 5 hours. Langmuir and Freundlich isotherm model gives a good fitting for the sorption process with high determination coefficient greater than 0.998. The parameter of this model shows a favorable sorption for removing benzene by GDAS. Intra-particle diffusion model data fitting shows two separate regions; the first severe portion attributed to the immediate sorption step and another portion is the intraparticle diffusion rate is dominated. The parameters of the model illustrate the external mass transport mechanisms must be considered with intra-particle diffusion.

    1. dear Saadat . Figure 1 represents to Energy-Dispersive X-ray Spectroscopy for sludge which analysis the chemical components of it.
      While Figure 2 described the structure of sludge by Scanning electron microscopy test.
