AB  - A new hybrid material was developed by the template-free hybridization of weak 
      acidic pink red B (APRB, C.I. 18073) with BaSO(4). The composition and structure 
      of the material were determined and characterized. In contrast to conventional 
      sorbents, the hybrid material has a specific surface area of 0.89 m(2)/g, but it 
      contains lots of negative charges and lipophilic groups as the basis of specific 
      adsorption. The efficient removal of cationic dyes and persistent organic 
      pollutants (POPs) indicates that it has an improved adsorption capacity and 
      selectivity with a short removal time less than 2 min; while the hybrid sorbents 
      fit the Langmuir isotherm model, and follow the octanol-water partition law. 
      Instead of using APRB reagent, an APRB-producing wastewater was reused to prepare 
      the cost-effective sorbent, and the equilibrium adsorption capacities of which 
      reached 222 and 160 mg/g for EV and BPR, respectively. The sorbents was then used 
      to treat three wastewater samples with satisfactory results of over 97% 
      decolonization and 88% COD-decreasing. In addition, the hybrid sorbent was 
      regenerated from sludge over five cycles, and its adsorption capacity was not 
      appreciably changed. This work has developed a simple and eco-friendly method for 
      synthesizing a practical and efficient sorbent.
