Abstract:
In developing country where cost is often an important factor, many studies were done to determine the effectiveness and reliable factors in removing heavy metals from wastewater using low cost absorbent. Thus, this study was focused on tea waste as an alternative absorbent in order to remove heavy metals and turbidity from synthetic wastewater. Batch experiments were conducted to determine the factors affecting adsorption of Pb and turbidity removal. Heavy metals contents in the sample solution were analyzed by Flame Atomic Absorption Spectrophotometry (AAS)while turbidity meter is used to determine turbidity removal. As the results, 96.4% of ions Pb removed using tea waste compared to only 10.5% ions Pb removed. This is to shows that tea waste is capable of binding appreciable amounts of Pb from Aqueous solutions. Besides, tea waste is turbidity of the synthetic wastewater. The adsorption capacity was the highest at solution pH range 5-6. Therefore, it is proven that the tea water can be used as alternative adsorbent to remove heavy metals and turbidity presence in the water and reduce cost of material.
