Competitive and cooperative simultaneous adsorptions of phenol and aniline from aqueous solutions by hyperemsslinked potymerie adsorbents(NDA103、NDA101、NDA100)were investigated．The results indicated that adsorption isotherills for them in both single and binary systems can be well fitted by the Langmuir equation．At the lower equilibrium concentrations

the individual adsorbed amounts of phenol or aniline on macroreticular adsorbents in single systems is higher than those in binary systems because of the competition between phenol and aniline towards the adsorption sites．It is noteworthy that at higher concentrations

the total uptake amounts of phenol and aniline in binary systems are obviously larger than the pure uptake amounts in single systems

and a large excess was noted on the particle surface at saturation

which is presumably due to the cooperative effect primarily arisen from the hydrogen bonding or weak acid—base interaction between phenol and aniline．Increasing temperature from 293 K to 313 K enhanced the cooperative effect on simultaneous adsorption of aniline and phenol on NDAl03；while

the cooperative coefficients on NDA101 and NDA100 almost kept unchanged．
