The bleaching efficiency of attapulgite is higher than oil palm ash (OPA) based adsorbent but it has higher efficiency than kaolin and mica . The results indicated that at time 60, 120, 180 and 240 min using constant volume of 1000 ml and temperature of 195 O C, the adsorption capacity Qt were 0.704, 0.776. 0.784 and 0.776 respectively. From the result, it was realized that the 180 min gave a good adsorption capacity close to unity. Also the efficiency of removal were also determined, which were all showing a good result from 88, 97 and 98%. 180 minute was able to have higher percentage removal which indicates that at 180minutes, equilibrium reach has higher adsorption capacity and percentage removal. evaluated the bleaching efficiency of Achalla Clay (ACC) by assessing factors like contact time, temperature, and adsorbent dosage. They set a baseline with an initial absorbance of 2.50 for ACC. In contrast, a study on attapulgite demonstrated high bleaching efficiency of 97-98%, particularly notable at a 3% dosage. The attapulgite study also suggested mica as a potential alternative due to its performance. While focused on time intervals, they didn't directly explore alternative materials but emphasized the impact of factors like dosage and temperature on bleaching efficiency. These studies collectively reveal the intricate dynamics influencing effective bleaching, highlighting attapulgite's efficiency and the potential of alternative materials.
