Abstract

- Active charcoal can be made from a variety of raw materials, one of which is the cassava skin because the skin has a carbon content of cassava 59,31%. One of the utilization of active charcoal is as adsorbents on purification of river water. Active charcoal cassava peels are made with the process of carbonization temperature 300ºC, 500ºC, and 700ºC in the furnace. Active charcoal that has been in the carbonization is enabeld NaOH concentrations variations 0,1 N; 0,2 N; and 0,3 N with a time of immersion for 24 hours. Then in contact with river water right for 30 minutes and analyzed metal absorption of Fe and Mn in the river water. This research it can be concluded that the best results for the absorption of metals Fe, namely at a temperature 700ºC and rhe concentration of NaOH 0,3 N obtained concentration absorption of 0 mg/mL (not detected), while for metal Mn at temperatures of 300ºC and the concentration of NaOH 0,3 N obtained concentration absorption of 0,213 mg/mL.
