Preparation method and application of sterilization activated carbon

The invention discloses a preparation method of sterilization activated carbon, which comprises the following steps of: weighing base carbon according to the mass, putting the base carbon into a dispersion liquid, carrying out ultrasonic treatment or stirring for dispersion treatment, standing and soaking for 0.5-1 hour, adding a pre-prepared impregnation liquid, uniformly mixing, soaking for 10-20 hours, carrying out vacuum centrifugal drying dehydration and cooling at 100-120 DEG C, carrying out granulation molding, carrying out drying activation on the granulated active carbon mixture in 110-140 DEG C high-temperature hot air for 2-5 h, cooling to 30-40 DEG C, and aging at 50-60 DEG C for 8 h or more to obtain the sterilization active carbon finished product. The prepared sterilizationactivated carbon has high-capacity adsorption capacity, sterilization performance and protection performance, is good in stability, and can activate oxygen in air and change the oxygen into active oxygen to kill bacteria and
