POTENSI ARANG AKTIF BAMBU BETUNG (Dendrocalamus asper) SEBAGAI ADSORBEN ION Mn2+ DAN NO3- DALAM AIR SUMUR BOR BURUK BAKUL, BENGKALIS

Abstract

The aim of this research was to determine the optimum ability of activated char of bamboo (Dendrocalamus asper) with variations concentration of Na2CO3 (2.5%, 5% and 7.5%) to adsorp Mn(II) (SNI 6989.16-2009) and nitrate (SNI 6989.8-2009) in the water sample, by doing preparation and characterization of activated char, analysis of boreholes water, and adsorption analysis. Activated char of bamboo was optimum by using 5% of Na2CO3.Characterization results showed that moisture content, ash content, and surface area was 3.05%, 3.67%, and 74.52 m2/g respectively. Adsorption of Mn(II) and nitrate was determined by using Atomic Adsorption of Spectrofotometer (AAS) and Spectrophotometer UV-Vis, respectively . The results showed that the optimum adsorption of activated char of bamboo for Mn(II) and nitrate ions was 74.57% and 60.60%, respectively.
