Paperback. Zustand: Very Good. In diesem Buch wird die Adsorption von Kupfer-Ionen auf den Bl ttern von Phoenix Dactylifera L. beschrieben. Es wird festgestellt, dass die Adsorptionsph nomene vom pH-Wert, der Adsorptionsmitteldosis, der Anfangskonzentration, der Temperatur und der R hrzeit abh ngig sind. Ferner wurde dieser Prozess mit Hilfe von Adsorptionsisothermen, n mlich Langmuir, Fruendlich, Temkin, Hasley, Jonovaic und so weiter, bewertet. Die kinetischen Modelle pseudo erster Ordnung, pseudo zweiter Ordnung, Elovich und Intrapartikeldiffusion wurden ebenfalls ausgewertet. Die optimalen Bedingungen f r die Aufnahme von Kupferionen sind pH = 1,5, Adsorptionsmitteldosis = 0,2 g, Anfangskonzentration = 10 ppm, R hrzeit = 30 Minuten. Die Adsorption wird am besten durch das Temkin-Adsorptionsisothermenmodell und das kinetische Pseudo-Modell zweiter Ordnung beschrieben. Die maximale Adsorptionskapazit t wurde mit 2,48 mg/g ermittelt.…
