Abstract
The nonionic surfactant phase adsorbed on silica gel is proposed as a new medium for the separation and concentration of trace metal chelate s. The 1-(2-pyridylazo)-2-naphthol chelates of Ni(II) and Zn(II) can b e concentrated into the nonionic surfactant phase on silica gel. It wa s found that these hydrophobic compounds were collected by dissolution into the surfactant assembly formed at the silica/water interface.
