✦ Synopsis

Based on earlier experiences with aand g-zirconium phosphate, zirconium phosphate-phosphite (ZrPP) containing silica (ZrSiPP) has been prepared, and its structure identified by XRD. The thermal behaviour and specific surface area have also been determined. On the basis of experimental data for SiZrPP, the following monoclinic cell parameters of: a 5 0.7622 nm, b 5 0.5956 nm, c 5 2.2105 nm and b 5 111.48 (different from those of ZrPP) were calculated. SiZrPP has five times higher 2 21 specific surface area (52.6 m ? g ) than ZrPP and it shows characteristic thermal decomposition.

In a recent paper we have demonstrated that chelating ion-exchange resins can be prepared in a short time with commercial adsorbent resin (XAD-2) and a water insoluble complexing agent (TAN or PAN). These resins have been applied to preconcentrate transition metals before their determination. In ord
