Özet

Polycondensation of ethylene diamine with p-dichloromethyl benzene in different molar ratios (0.8-1.5) gives mostly crosslinked polymers. These resinous polymers are water-compatible and have moderate swelling ability (swelling rate 1.6-20) in water depending on the pH of the solutions. The free amine state of the resinous polymers are capable of chelating with various transition-metal ions such as Cu(II), NI(II), Co(II), Cd(II), and Zn(II), even in very low concentrations. Due to rapid complexation, high metal binding capacity, and ease of regenerability, these resins can be useful for the removal and recovery of transition-metal ions from water solutions.
