| Abstract |
Laboratory studies were carried out to find out the characteristics of humic acid treatment by activated carbon and ionized gas. In order to increase oxidation power of ionized gas for treating organic matter, we used granular activated carbon. By using UV_(254), easy analysis method, we calculated humic acid concentration and SCODcr concentration. For an initial concentration of humic acid, 10, 50 and 100ppm, the reaction rate constant by UV_(254) was 8.98×10 /min, 5.62×10^(-3) /min and 4.8×10^(-3)/min respectively due to the same flow rate of ionized gas. When we added activated carbon to the ionized gas for humic acid treatment, the reaction rate constant increased in 4.13, 3.65 and 3.15 times. So, by using activated carbon in treating humic acid by ionized gas, oxidation power of organic matter by ionized gas was increased. The hydrophobic fraction constitutes 98% of organic matter for humic acid at the beginning. After the treatment using ionized gas for humic acid, the hydrophobic fraction decreased by 63 -65% and the hydrophilic one increased by 35 -37%. So, it was proved that the treatment increased the hydrophilic fraction in organic matter. |
