Abstrakt: The purpose of this study is to create a method for removing thorium (IV) ions utilising two classes of adsorptive material (such as cinnamon bark powder and Pongamiapinnata leaves), both of which have shown promise in previous studies. To determine the adsorbent's chemical make-up, we performed FTIR and SEM-EDX analysis. Maximal Th (IV) ion saturation through cinnamon bark under analyzing situations (initial concentration(1 mgL−1), bed depth(5cm), and a flow rate of (2.5 ml min−1) was 90% for 40 minutes at a 4.5 pH, and by Karanja leaves under analysing conditions was 89% for 40 minutes at a pH of 3.0. After testing the adsorbents for their ability to remove Th (IV), it was determined that cinnamon bark was the most effective. It was discovered that Thomas's model works properly suited cinnamon bark adsorption data for thorium (IV) ions (R2 = 0.99) and Pongamiapinnata leaves (R2 = 0.89) where the Adams-Bohart model and the Yoon model failed.
