Abstract
The abilities of different types of wood sawdust and wood originate materials for removing some toxic heavy metal ions from water were investigated. Sawdust of poplar, willow, fir, oak and black locust wood, pulp and Kraft lignin were used as adsorbents. The effects of contact time, pH, metal concentration and sawdust particle size on the removal of Cu(II) ions by poplar sawdust have been studied. Leaching from these adsorbents into water during adsorption was also investigated.
Zusammenfassung
Das Potenzial von Holzmehl aus verschiedenen Holzarten zum Entfernen von toxischen Schwermetallionen aus wässrigen Lösungen wurde untersucht. Neben Holzmehl von Pappel, Weide, Tanne, Eiche und Robinie wurden auch Zellstoff und Kraft-Lignin als Adsorbentien eingesetzt. Untersucht wurde der Einfluss der Behandlungszeit, des pH, der Metallkonzentration und der Partikelgröße auf das Entfernen von Cu(II)-Ionen durch Pappel-Sägemehl. Das teilweise Auflösen dieser Adsorbentien in Wasser während der Adsorption wurde ebenfalls untersucht.
