PEMANFAATAN ARANG AKTIF KAYU RAMBAI (Sonneratia Acida Linn) DENGAN AKTIVATOR NATRIUM KARBONAT 5 % UNTUK MENURUNKAN KADAR BESI (Fe) DALAM AIR SUMUR
Abstract: The objectives of
this research is to find out the effectiveness of activated
Rambai wood (Sonneratia acida Linn) charcoal to decrease Fe content of
digging well water in Banjarbaru. Factorial completely randomized design are
applied on data analysis. Activator used in activating charcoal is 5 % Sodium
carbonate. Two factors are activated charcoal concentration (8 %, 10 % and 12
%) and time adsorbing ( 4 hours and 6 hours). Fe content in the water before
treatment is 2.6582 ppm. The best treatment is 4 hours adsorbing time with 10 %
charcoal concentration, adsorbed 90.7 % (2.355 ppm) Fe content. 8 % charcoal
concentration is not enough to decrease Fe content of the digging well water to
be healthy drinking water (healthy standard for Fe content is less than 1.0
ml/l).
Key words: Activated charcoal,
Fe content, adsorb
