AB  - Acid modified clinoptilolite are usually used as adsorbents 
  for NH<SUB>3</SUB>, heavy metals and organic contaminants. Acid-modified clinoptilolite 
  was prepared using the method of ion exchange reaction at 80&deg;C for 4 h and 
  used for bacteria and toxins adsorption which are significant for providing 
  mechanism for the adsorption of microorganisms <I>in vitro</I>. XRD, SEM, AFM, 
  BET and micropore volume were used to characterize parent clinoptilolite and 
  acid modified clinoptilolite. Cation Exchange Capacity (CEC) was used to determine 
  changes of adsorption ability before and after modification. The acid-modified 
  clinoptilolite showed the strong adsorptive in the rang of 20-25 mg g<SUP>-1</SUP> 
  when the initial bacterial suspension concentration was 1x10<SUP>8</SUP> Colony 
  Forming Units (CFU)/mL. The adsorption capacities of acid-modified clinoptilolite 
  for all bacterial suspension increased with an increase of initial bacterial 
  suspension concentration. An increase of adsorption capability of acid-modified 
  clinoptilolite was attributed to the BET and micropore volume. These results 
  indicated the competency of acid-modified clinoptilolite adsorbent for bacteria 
  adsorption.
