ABSTRACT:
Pharmaceutically useful trace elements contained in human urine are collected by disposing a filter body containing an adsorbent for the trace elements in the gravity flow line connecting the unflushed urinal of a portable toilet to its holding tank. The portable toilet also includes a seat connected to the holding tank by a separate gravity feed line. The holding tank contains an odor reducing chemical solution for the urine and fesces. A filter body supported in the conduit between the urinal and the holding tank consists of an adsorbent for the trace constituents of the urine that it is desired to extract. Urine voided into the urinal passes through the adsorbent filter body before going to the holding tank. When the holding tank of the portable toilet is pumped clean and the deoderizing solution replaced, the filter body is removed and processed to extract the trace constituents replaced with an unsaturated filter body.
