AB -  Abstract A novel monolithic column containing large interconnected pores was simply prepared from epoxy resin and triethylenetetramine (TETA) and pore‐forming reagent (polyethylene glycol, PEG‐1000) by in‐situ polymerization. PEG‐1000 was both solvent at the initial stage and phase‐separation reagent at the later stage of polymerization reaction. Its structure was characterized by Fourier transform‐infrared spectra (FTIR) and scanning electron microscopy (SEM), respectively. The results showed that the pore characteristics of monoliths depended strongly on the amount of PEG‐1000. A column method has been established for the preconcentration and determination of copper(II) combined with inductively coupled plasma atomic emission spectroscopy (ICP‐AES), using a simple glass‐tipped tube. The adsorption‐desorption characteristics of the monoliths for Cu(II) in aqueous solution were investigated in detail. The ion concentrations in batch adsorption experiments were determined by ICP‐AES. Copper ions could form complexes with the amino groups of the monoliths, and be quantitatively retained in the pH ranges of 5.0–9.0. The uploaded column was eluted by 1.0 mol L−1 HNO3 and recovery of Cu(II) was more than 97%.
