EFFECTIVENESS OF ADSORBENTS CHICKEN EGGSHELLS AND CASSAVA SKIN TO REDUCE POLLUTANTS IN THE ELECTROPLATING INDUSTRYMuhammad Al Kholif, Pungut, Sugito and Djoko Adi WalujoAbstract The electroplating industry has toxic content that is toxic to living things and the environment. This study aims to examine the values of Cu and Cr levels in the electroplating industry based on variations in adsorbent weight comparison. Adsorbents used are chicken eggshell and cassava skin with a contact time of 90 minutes. Adsorbent comparison used is 20:10, 25:10, and 30:10. After processing by applying the adsorbent system in the electroplating industry wastewater obtained the results of research it appears that the comparison of the weight of adsorbents influenced the decline of Cu and Cr metals with a decrease in Cu by 0.003 mg/l or with the efficiency of 99.43% and a decrease in Cr by 0.962 mg/l or with an efficiency of 95.44%. |
