The sorption capacity of Japanese cedar wood powder (CWP) for the recovery of Au III is studied by varying its morphology and the experimental conditions. The results show that CWP is a stable, “green” sorbent with a high capacity and selectivity and allows recovery by a dual mechanism of sorption and continuous reduction. The reduction process forms hexagonal and triangular gold particles of 2–5 μm (see figure).
