Synthesis, characterization of low density polyhydroxy polyurethane foam and its application for separation and determination of gold in water and ores samples

- A new inexpensive polymeric adsorbent was prepared from polyurethane foam (LPPF).
- The character of LPPF makes it suitable to recovery gold from real sample.
- It has low density, high sorption capacity and very fast gold extraction.
- The LPPF was regenerated and reused cycles without decreasing their capacities.
- A simple and sensitive detection for nano-determination of gold has been developed.
