The existing disinfection powder mainly comprises potassium hydrogen peroxymonosulfate, chlorine dioxide, sodium dichloroisocyanurate, trichloroisocyanuric acid, dibromohydantoin disinfection powder and the like. The potassium hydrogen peroxymonosulfate complex salt can generate active oxygen after being dissolved in water, can rapidly oxidize the microbial cell wall, and can generate free hydroxyl groups to rapidly inactivate microbial proteins. However, the powder is easy to absorb moisture and decompose to lose the disinfection effect, and when the aqueous solution is disinfected in an atomization mode, potassium hydrogen persulfate is easy to separate out to block the atomization device. Chlorine dioxide disinfection can quickly kill bacteria, fungi, viruses, spores and the like, is generally prepared on site by using hypochlorite, but has residual byproducts and brings safety problems to human bodies. Most of the chlorine dioxide disinfection powder at present adopts a binary packaging mode, and the use is relatively complex. Trichloroisocyanuric acid, dibromohydantoin and the like are dissolved in water to generate hypochlorous acid so as to achieve the aim of disinfection, but the trichloroisocyanuric acid and the dibromohydantoin have poor water solubility, and the disinfection capacity of the trichloroisocyanuric acid and the dibromohydantoin is greatly reduced.

As can be seen from the results of table 2, the effective chlorine in the disinfectant prepared from the disinfectant can be stabilized after the active chlorine stabilizer is added, the effective chlorine drop rate is lower than 10% even after the disinfectant is placed for 14 days, the effective chlorine drop is obvious without the active chlorine stabilizer in comparative example 1, the disinfectant is faded, the active chlorine indicator can be used for judging whether the disinfectant is effective, the effective chlorine indicator is not added in comparative example 2, the disinfectant is colorless and transparent, and the disinfectant effect cannot be simply judged; comparative example 4 illustrates that carmine and amaranth need to be in acidic conditions when used as an indicator of available chlorine. Under neutral conditions, N-diethyl p-phenylenediamine sulfate is selected as an effective chlorine indicator; comparative example 6 demonstrates that carmine can quickly undergo a photoreduction reaction to fade without the addition of an active chlorine source, and the color itself does not interfere with the judgment of the activity of the disinfectant; comparative example 7 illustrates that the synergist does not affect the stability of the disinfectant.
The sterilization solutions prepared in the above examples and comparative examples were subjected to a sterilization test, and the test method was performed with reference to "sterilization technical Specification" (2002 edition), and the results are shown in Table 3.
TABLE 3 Table 3
From the results of Table 3, it can be seen that the disinfectant prepared by using the disinfectant powder of the present invention can rapidly kill bacteria. Comparative example 6 was unable to achieve bacterial kill without the addition of an active chlorine source. Comparative example 7 illustrates that the potentiating agent is effective in assisting the killing of bacteria by the active chlorine source.
In conclusion, the disinfectant prepared from the long-acting disinfectant powder has high stability, can provide active chlorine for a long time, can judge whether the disinfectant powder fails or not through color, and can effectively kill various bacteria.
