英文摘要	To remove nitro aromatic compounds (NACs) from 2,4,6-trinitrotoluene (TNT) red water, large-pore-size (pore size?=?200?nm) polystyrene (PSt) microspheres were activated with chloroacetyl chloride followed by reaction with 1,2-ethanediamine (EDA). Fourier transform IR analyses showed that the amino group was introduced onto PSt microspheres. Determination of the total amino group and primary amino densities suggested that the imino group was the functional group of EDAPSt. Scanning electron microscope images and mercury porosimetry measurements indicated that the pore structure was well maintained during the reaction. After adsorption with EDAPSt, 98.5% chemical oxygen demand and 99% acute toxicity of TNT red water was removed. As shown by HPLC and GCMS, all the neutral and acid NACs in TNT red water were removed by EDAPSt, while the basic NACs were not. The results showed that hydrogen bonding and electrostatic attraction were involved in adsorption. The adsorbed neutral and acid NACs were eluted using methanol and 0.1?mol?L-1 NaOH, respectively.; Environmental Sciences; Marine & Freshwater Biology; Water Resources; SCI(E); 5; ARTICLE; 8; 823-829; 40
