| Abstract: | Piperine, an alkaloid derived from the fruits of Piper nigrum, has been tested as an extracting bioreagent for gold. It has been observed that piperine as well as the fruits of Piper nigrum itself can act as an efficient exchanger for gold both in trace and macro scale. The accumulation of gold by these bioreagents
is highly pH dependent. |
