About the Book

Untersucht wurde die Biosorption von Cadmium(II)-Ionen aus wässrigen Lösungen an Eierschalen (Gallus domesticus). Die IR-Spektroskopie und der Nullpunkt der Ladung wurden zur Charakterisierung des Biosorptionsmittels verwendet, um die funktionellen Gruppen bzw. die Ladung des Materials zu ermitteln. Es wurden Batch-Experimente durchgeführt, um den Biosorptionsmechanismus besser zu verstehen und auch die Auswirkungen einiger wichtiger Parameter wie Biosorptionsmitteldosierung, Kontaktzeit, Anfangskonzentration des Schadstoffs und pH-Wert der Lösung zu untersuchen, die die Biosorption beeinflussen. Der maximale Prozentsatz der Entfernung von Cadmium(II)-Ionen (99,5%) wurde bei 100 mg des behandelten Biosorptionsmittels, einer Kontaktzeit von 30 Minuten und einem pH-Wert von 4,5 erreicht. Die experimentellen Daten passten am besten zum Langmuir-Modell mit R2 = 0,994. Die Ergebnisse der Kinetik-Studie zeigen, dass das Modell pseudo-zweiter Ordnung dasjenige mit dem besten Bestimmtheitsmaß (R2 = 0,999) ist, und die Diffusionsstudien zeigten drei lineare Anteile (R12 = 1 und R22 = 0,989 und R32 = 0,707). Aufgrund dieser Ergebnisse können wir empfehlen, dass Eierschalen als effektives und kostengünstiges Biosorptionsmittel zur Entfernung von Cadmium(II)-Ionen aus dem Abwasser verwendet werden können.
