摘 要：<正>Magnetic polyethyleneimine chelating resin（PEI2） was prepared. Its average diameter was 0. 44mm and it contained magneticparticles over 11% of the microcapsules after it had been treated with 8%hot HCl. The results showed that tbe reaction media had significant effecton Physical forms,magnetic particles content and stability in acid of themicrocapsules.PEI2 bad very high adsorption capacity to Au3+,Pb2+ andHg2+,and little one towards Mg2+,Pb2+ and Cu2+.It was discoveredthat PEI2 could reduce Au3+ into elemental gold.
