| Research Abstract |
The fate of micro-organic pollutants(e. g., pharmaceuticals and environmental hormones with the formation of struvite(MAP) from human urine was experimentally investigated. It was found that most micro-organic pollutants in human urine were not transferred in the MAP with exception of a few pharmaceuticals. Other findings were that the optimum amount of Mg added for the MAP formation is twice of the amount of phosphorus in the human urine, the optimum pH condition is attained with the pre-storage of human urine, the transfer of micro-organic pollutants into MAP can be minimized with the pre-storage.
