AB  - Adsorbent materials created from wastewater sludge have unique surface 
      characteristics and could be effective in adsorption applications. In this 
      research, the sludge-adsorbents were generated by pyrolyzing mixtures of sewage 
      sludge and H(2)SO(4). Scanning electron microscope (SEM), thermal analysis, X-ray 
      diffraction (XRD) and X-ray photoelectron spectroscope (XPS) were used to analyze 
      the properties of sludge-adsorbent. XPS results show that the adsorbent surface 
      functional groups with high contents of oxygen-containing groups serve as active 
      sites for the adsorption and affect the surface characteristics; the adsorption 
      mechanism of methylene blue (MB) is mainly Bronsted acid-base reaction between 
      the adsorbent surface and MB; and iodine atoms are bonded to the surface of the 
      adsorbent mainly by dispersive interactions rather than by electrostatic 
      interactions. The results also show that H(2)SO(4) level, pyrolysis temperature 
      and sulfuric acid/sludge weight ratio actually affected the adsorption 
      characteristics. Using the conditions (H(2)SO(4) level of 1-18 M, pyrolysis 
      temperature of 650 degrees C, and weight ratio of 0.8), the adsorption capacities for MB 
      and iodine were 74.7-62.3 mg g(-1) and 169.5-209.3 mg g(-1), respectively.
