A detailed diagram illustrating a Redox Reaction with Activated Carbon, showing Chloramine reduction and Ozone catalysis to O2 and CO2.

1. Reaktion: CO + 2 NH₂Cl → C + 2 HCl + N₂ + H₂O Diese Reaktion beschreibt, wie Chloramine durch Aktivkohle abgebaut werden. 🔍 Wichtige Fachbegriffe Chloramine (NH₂Cl): Desinfektionsmittel im Wasser, entstehen z. B. in Schwimmbädern. Sie sind unerwünscht, weil sie Geruch und Reizungen verursachen. Reduktion: Ein Stoff nimmt Elektronen auf. Oxidation: Ein Stoff gibt Elektronen ab. Redoxreaktion: Eine Reaktion, bei der gleichzeitig Oxidation und Reduktion stattfinden. Katalyse: Ein Stoff (hier Aktivkohle) beschleunigt eine Reaktion, ohne selbst verbraucht zu werden. 🧩 Was passiert in der Reaktion? Das Chloramin (NH₂Cl) wird reduziert → es zerfällt in: N₂ (Stickstoffgas) H₂O (Wasser) HCl (Salzsäure) Das CO und die Aktivkohle wirken als Reduktionsmittel (sie geben Elektronen ab). Dabei entsteht elementarer Kohlenstoff (C). 🟦 Bezug zu Aktivkohlefiltern Aktivkohle entfernt Chloramine nicht nur durch Adsorption (Anlagerung an der Oberfläche), sondern auch durch chemischen Abbau: Chloramine werden zerlegt. Die Produkte sind harmlos. Die Aktivkohleoberfläche wird dabei leicht verändert, bleibt aber funktionsfähig. 🧪 2. Reaktion: 2 O₃ + C → 2 O₂ + CO₂ Diese Reaktion beschreibt, wie Ozon durch Aktivkohle abgebaut wird. 🔍 Wichtige Fachbegriffe Ozon (O₃): Sehr reaktives Gas, das in hohen Konzentrationen gesundheitsschädlich ist. Oxidationsmittel: Ein Stoff, der andere Stoffe oxidiert (ihnen Elektronen entzieht). Oxidation von Kohlenstoff: Kohlenstoff wird zu CO₂ umgewandelt. 🧩 Was Mehr sehen
