II. MATERIALS AND METHODS
1. Preparation and Properties of Functional Ceramic Ball ocher Analysis
Food waste clay, loess and loess mixed with ball According to previous studies, 10) food produced proper mixing ratio 30%, 50% loess was found to be waste, soil 20%. The activated carbon is pulverized food waste study 1 with respect to weight, with 3, 5, 7, was prepared by mixing 10% of yellow dust The result can be seen
in the presence of activated carbon adsorption Happened. For this purpose, the mixing amount incorporated for each and W for about 24 hours after forming a spherical dough here Kite 105oC for 2 hours in a hot air gun to dry in oven , 900 ± 10oC Article by baking for one hour in the electric furnace Which was completed.

Soil physical properties of the yellow ball up in the preparation of each of these evaluation conditions The compressive strength, measured hayeotneun porosity, water absorption, and a specific surface area Instron having compressive strength power meter (Model 1011) The porosity and water absorption was measured using KSL Measure 11 was measured as the way to 3114).
It was analyzed using a. In addition, ball up yellow dust levels And in the form of a scanning electron microscope (scanning electron Microscope: SEM, DSM940A, Germany) made by Shooting W was observed.
2. Functional ceramic ball ocher adsorption performance evaluation
According to the internal activity of a mixture of loess ball crushing activated carbon ratio Absorb iodine adsorption of carbon residues to evaluate performance Strength tests were conducted. Water treatment standards and specifications Analysis And display reliability tests were performed according to standard 12), 5 loess ball made in accordance with the mixing ratio of each crushing activated carbon A mixture and then by a kty- A-5101 pulverized 325 KS At 0.5 g Pyojunche through the mesh (45 μm or less) The temperature of the room, it was mixed with 50 ml of 0.1 N iodine solution Using tanggi was stirred for 15 minutes. The Match After centrifugation at 2,000 RPM supernatant was right 10 mm Taking titration with 0.1 N sodium thiosulfate solution absorbed through This amount was calculated.
In addition, a ball made of loess according to the mixing ratio of pulverized activated carbon Methylene blue absorption column can absorb experiences for performance analysis Internal diameter 4.5 cm, height 50 cm, using rows, columns were A transparent acrylic cylinder as standard effective dose of 700 ml Produced by FIG. The 1 was prepared as follows. Loess ball on each column About 50%, and receiving 200 mg / L concentration methylene blue filling Columns treated fairly low amount of mixing liquid Giseok acid was fed to install the air.
2000 Sampling 2 minutes is collected every 10 ml The supernatant with respect to the UV 655 nm RPM was centrifuged Standing was measured and the absorbance, methylene blue calculating the amount of adsorption It was to create a calibration curve.
