摘 要:通過(guò)對高嶺土進(jìn)行表面改性制備了高嶺土 MBT復合體 ,并考察了其對水溶液中某些重金屬離子的吸附性能。結果表明 :高嶺土 MBT復合體對水中Pb2 +、Hg2 +、Zn2 +的吸附能力明顯優(yōu)于純高嶺土和僅經(jīng)過(guò)表面處理的高嶺土 ,其對Pb2 +、Hg2 +、Zn2 +的最大吸附量分別為 16 91μmol·g- 1、2 0 5 2 μmol·g- 1和 10 80 μmol·g- 1。 |

Abstract:The kaolinite 2 Mercaptobeniazole complex was prepared and its adsorbability of some heavy mental ions in solution was investigated.It was proved that its adsorbability(of Pb 2+ ?Hg 2+ ?Zn 2+ )was much better than that of the pure kaolinite or that of the kaolinite which was only modified on surface.The maxim adsorption of Pb 2+ ,Hg 2+ ,Zn 2+ by Kaolinite 2 Mercaptobeniazole was 16.91μmol·g -1 ,20.52μmol·g -1 ,10 80μmol·g -1 respectively. |
Key words:kaolinite 2 mercaptobeniazole; heavy mental ions; absorbability |
