Example Embodiment
[0050] Example 1
[0051] 12.4 g of water, 15.6 g of a 48% by weight aqueous sodium hydroxide solution, 12.0 g of sulfamic acid, and 60.0 g of a 12% by weight sodium hypochlorite aqueous solution were mixed to prepare a bactericidal algicide composition. The pH value of the fungicide and algicide composition is 13.4.
[0052] The residual chlorine concentration of the fungicide and algicide composition was 7.2% by weight immediately after preparation, 7.0% by weight 6 days later, 6.9% by weight 14 days later, and 6.8% by weight 20 days after standing at 40°C. Moreover, when left still at 60 degreeC, it was 7.2 weight% immediately after preparation, it was 6.2 weight% after 6 days, it was 4.9 weight% after 14 days, and it was 4.8 weight% after 20 days.
Example Embodiment
[0053] Example 2
[0054] Except having changed the water compounding quantity into 8.7g and 48 weight% sodium hydroxide aqueous solution into 19.3g, it carried out similarly to Example 1, and produced the microbicide and algicide composition. The pH value of the fungicide and algicide composition is 13.8. The residual chlorine concentration was measured in the same manner as in Example 1.
Example Embodiment
[0055] Example 3
[0056] 11.9 g of water, 15.6 g of 48% by weight sodium hydroxide aqueous solution, 12.0 g of sulfamic acid, 60.0 g of 12% by weight sodium hypochlorite aqueous solution, and 0.5 g of benzotriazole were mixed to prepare a fungicide and algicide composition. The pH value of the fungicide and algicide composition is 13.4. The residual chlorine concentration was measured in the same manner as in Example 1.
