Analysis of metals storage capacity in Pleurotus salmoneostramineus as an alternative recycling approach
摘要
Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) and Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) were used to study the incorporation of different metals in rose mushroom. Electronic waste material was simulated by metals, which were added as powders to the soil. The results indicate that some metals, like the rare earth metals dysprosium and praseodymium, and also other valuable metals, like cobalt, germanium, rhodium, ruthenium or vanadium, can be accumulated in the Pleurotus salmoneostramineus. On the other hand, there seems to be no relative accumulation for tungsten. This might be due to the specific transport or storage mechanism of the chemical elements in the organic material. Scanning electron micrographs (SEM) give indication about metals storage capacity within the fungi material.
