dc.description.abstractManufacturing and testing of magnetic carbon of rubber wood sawdust mixture and for heavy metal absorption of iron in water samples Drilling, Well Water Excavation in Dumai, has been investigated the magnetic carbon begins with a pre-carbonization process at a temperature of 280oC in a vacuum. Milling and sieving process to obtain the carbon particle size is less than 38 μm, the increment in the surface area of the carbon is done by using a chemical activation with potassium hydroxide (KOH), the activator weight ratio of KOH and carbon powder was 4: 1. The carbon is then neutralized by using distilled water and a solution of chloride acide (HCl) repeated until the pH of the washing water became neutral. Furthermore,the activated carbon powder mixed uses powder with a ratio of 5: 4. Mixture is done by using a mortar and proceeded with the process ball milling for 2 hours. Finally, a mixture of carbon powder and is carbonized at 850 °C at N2 gas and then followed by washing and drying to produce a magnetic carbon . The testing of Fe ion absorption from water sample, Water Well Drilling Excavation and filtered in Dumai is done every 2 hours. The results at atomic absorption spectroscopy showed that the increment of absorption after 2 hours has water absorption percentage of 97.94% Drilling, Well Water Excavation amounted of 83.58 % Minerals and Water Drilling filtered by 56.18% with the use of magnetic . Testing X-ray diffraction showed peaks Fe 2θ = 36o angle and Scanning Electron Microscopy shows the particle size is similar to irregular shapes and whitish. Dispersive energy X-rays have shown the presence of Fe in the magnetic carbon absorbent material of rubber wood sawdust.en_US
