摘要：

A one-step Mannich reaction has been developed for the immobilization of 8-quinolinol on aminopropylsilica gel that results in a product exhibiting a capacity of 466 +/- 20 mu mol g(-1) for copper(II) ions. Capacity measurements were made by copper(II) uptake and elemental analysis. Characterization of the silica bound ligands in this synthetic context including IR spectrometry, C-13 NMR spectrometry, acid-base properties and stabilities were presented. The effect of pH on the extraction of copper(II), nickel(II) and cadmium(II) for silica-immobilized 8-quinolinol was also evaluated.
