PURPOSE: Provided are loess ball deodorants which remove the odor efficiently by using the domestically abundant loess and photocatalyst, and a preparation method thereof. CONSTITUTION: The loess ball deodorants are characterized in that loess balls(1) containing the copper powders are formed to have the diameter of 1 mm to 10 mm, the loess balls are coated with the photocatalyst(2), and the density is 0.5 g/ml to 0.95 g/ml. The preparation method of the loess ball deodorant comprises a formation step of the loess ball to mix the loess powders and water homogeneously and form into balls(1) having the diameter of 1 to 10 mm, a drying step to dry the loess balls at the temperature of at least 80 deg.C for at least 1 hour, a coating step to coat the loess ball with the TiO2 photocatalyst(2), and a sintering step to sinter the ball at the temperature of at least 600 deg.C for at least 12 hours. |
