Pembuatan Filter Berbasis Karbon Sekam Padi dan Zeolit Sintesis sebagai Pereduksi Ion Logam Pb dan Mn pada Air Sumur

Abstract

In this study, a filter based on carbon from rice husk and synthetic zeolite was made for well water. First the rice husk is pulverized and then carbonized with temperature variations of 700oC, 800oC, and 900oC. Then the sample was printed on a size of 3 cm x 3 cm x 1 cm with a pressure of 3 tons for 15 minutes. The results obtained with the most effective filtration value of manganese metal (Mn) from the initial content of 3.386468 mg/L with a filtration result of 0.000128 mg/L with a percentage adsoption capacity 0.0038%, while the effective filtration of lead metal (Pb) from the initial content of 0.000862 mg/L with a filtration result of 0.000013 mg/L with a percentage adsoption capacity 1,5081%. For the results of surface morphology and element content in samples using SEM-EDX, in this study the dominating element values were carbon (C) by 50.7%, oxygen (O) 31.6%, silica (Si) 15.7% and aluminum (Al) 2% in the best sample while in the lowest sample the carbon (C) element was 43%, oxygen (O) 35.4%, silica (Si) 19.8% and aluminum (Al) 0.9%. The adsorption efficiency for manganese metal (Mn) was 99.99% while the adsorption efficiency for lead metal (Pb) was 98.49%.
