## Abstract Carbon nanotubes (CNTs) were used as adsorbent to remove fulvic acids (FA) from aqueous solutions. The adsorption capacity of CNTs for FA can reach 24 mg g^β1^ at 5 Β°C and equilibrium concentration of 18 mg dm^β3^. The kinetic and thermodynamic parameters, such as rate of adsorption, st
