摘要：

Crosslinked adsorbents based on N-vinylpyrrolidone and N-vinylcaprolactam are synthesized by free radical copolymerization; their adsorption properties for 4-nitrophenol are studied under batch and dynamic conditions. A method for preconcentrating 4-nitrophenol from dilute aqueous solutions is developed.
