-
A phenolic polymeric pseudo crown ether(POCE) was directly synthersized from phenoxy ethanol and formaldehyde in one step. The phenolic resinification was studied by infrared spectrometry. The results show that besides the proportion of phenoxy ethanol to formaldehyde, reaction temperature and time, the crux is the amount of concentrated sulphuric acid used in phenol fromaldehyde condensation when 2-phenoxy ethanol is used as monomer. The polymer has good adsorption properties for Na+, K+, Ca2+, Sr2+, Hg2+, Cu2+, the adsorption capacities are 1.525, 0.849, 2.027, 0.709, 0.815 and 0.406 mmol/g, respectively.
