Iminodiacetic acid latex particles (IDA-Latex)

  • are monodisperse polymer particles with a very high density of iminodiacetic acid (IDA)-groups or NH2 groups on the surface,

  • have a mean particle diameter of about 300 nm,

  • show a very high binding capacity for trace metals (e.g. Mn, Co, Ni, Cu, Zn, Cd, Pb, U) in neutral to basic pH-range,

  • bind e.g. about 200 µmol Nickel(II)-ions per g of IDA-latex.
