Abstract

The  objective  of  the present  study  was  increasing  the adsorption activities of  zeolites  for organic  pollutants.  For  this  purpose  it  was  realize  the  using  of  modified  by  quaternary  ammonium salts natural zeolite. Natural zeolites and them modified analogs  can be made a renewable resource.
The  advantages  of  natural  by-products  in  comparison  with  other  sorbents  are  their  low  cost, availability of extraction, operational flexibility and control and others. Motor  transportation  and  auto  repairs  station  wastewaters  include  typical  sewage  from  the petrochemical and petrol using industries, of course in smaller amounts. Adsorption  from  wastewater  with  organic  pollutants  involves  concentration  of  the  solute  on  the surface.  Here,  it  has  been  had adsorption  and  desorption  process  together  which  will  attain  an equilibrium  state.  We  used  Freundlich  model  for  description  of  the  adsorption  data  for  activated carbon.
