## 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
A gas chromatographic-mass spectrometric method, combining an O-(2,3,4,5,6-pentaΓuorobenzyl)hydroxylaminediazomethane double derivatization, was developed to identify major keto acids in ozonated fulvic acid solutions. Three keto acids, glyoxylic, pyruvic, and ketomalonic acid, four aldehydes and tw
