い。(57) [Problem] To provide a method for disinfecting a sandbox, which can sterilize the sandbox without incurring any cost and without adversely affecting a human body and without being washed away by rain. SOLUTION: When disinfecting bacteria including Escherichia coli in a sandbox, a liquid is prepared by mixing powdery particles of titanium oxide (TiO 2 ) with water, alcohol, and an inorganic binder in the sand in the sandbox. Spray on sand in sandbox. Thereby, the countless titanium oxide particles contained in the liquid,
The titanium oxide particles flow into the interior from the sand located above the sand pit, and the titanium oxide particles are attached to the sand particles as the alcohol evaporates. Once the titanium oxide particles adhere to the sand particles,
The titanium oxide particles are less likely to be separated from the sand particles, so that the titanium oxide particles do not move down or out of the sandpit due to rain and do not run off the sandpit.

る。However, the method of spraying a disinfecting solution is not preferable when considering the effect on the human body. Also, when it rains, the disinfectant is washed away by rain,
Since the water penetrates into the ground or flows out of the sand pit, it is necessary to spray a disinfectant every time it rains in order to maintain the sterilizing action, and the amount of use and labor is enormous, and the feasibility is poor. On the other hand, in recent years, attention has been paid to titanium oxide (TiO 2 ), which has a photocatalytic reaction when exposed to light even at room temperature and exhibits an air purification function, a deodorization function, and an antifouling function. And it is also known to have a bactericidal action. The present invention has been devised by paying attention to such titanium oxide (TiO 2 ).
Another object of the present invention is to provide a method for disinfecting a sandbox without incurring a risk of being washed away by rain and capable of disinfecting the sandbox.

す。Next, an embodiment of the present invention will be described. In the present invention, when sterilizing bacteria including Escherichia coli in a sand pit, a liquid in which powdery particles of titanium oxide (TiO 2 ), water, an alcohol, and an inorganic binder are mixed in the sand in the sand pit, and this liquid is formed. Spray on sand in sandbox. As a result, a myriad of titanium oxide particles contained in the liquid flow downward from the sand located above the sandpit into the sand, and as the water and alcohol evaporate, the titanium oxide particles adhere to the sand particles. You. Once the titanium oxide particles are attached to the sand particles, the titanium oxide particles are less likely to be detached from the sand particles, so that the titanium oxide particles cannot move down or escape from the sandpit due to rain. No, do not run off the sandbox. Table 1 shows the test results when the liquid containing the titanium oxide particles was sprayed on the sand.

なる。In Table 1, A is sand only, B is sand 100
50 g of a liquid containing 10% by weight of titanium oxide particles with respect to 100 g, and C shows a case where 50 g of a liquid containing 20% by weight of titanium oxide particles are sprayed with 100 g of sand, and one week has passed. The figure shows the value of the bacterial count measured by sampling from a depth of 5 cm from the surface on the back sand. As is clear from this table, increasing the number of titanium oxide particles sprayed on the sand reduces the number of general bacteria from about 1/5 to 1/40 and the number of coliforms below the detection limit. It was found to be significantly reduced. In addition, the titanium oxide particles attached to the sand particles are not easily separated from the sand particles, and do not flow away from the sandpit even if it rains,
Conversely, the dirt on the surface of the titanium oxide particles is washed away by the rain, and its germicidal action is guaranteed for a long time.
