Abstract

|
|
This study was examined adsorption ability of heavy metal Hg(Ⅰ), Pb(Ⅱ), and U(Ⅵ) ion use of fruit from schizandra chinensis. The fruits of schizandra chinensis sample used breaking into fragments 50 ~ 100 mesh. The sample solution was mixed fruits of schizandra chinensis and heavy metal ion. Each heavy metal ion of into solution was quantum analysis with ICP-AES. As the result, each condition of maxium adsorption ability of heavy metal ion was high in the range of pH 5-7, adsorption time was about 15 minutes, and the optimum temperature was l00℃. The heavy metal ion was increased adsorption in order of increasing concentration and in ethanol solution better than in aqueous solution.
