Abstract
The invention discloses a method for making activated carbon by using wild peach pit shells. The method comprises the steps that the wild peach pit shells are dried for 12 hours at the temperature of 120DEG C to be dewatered, and are smashed to penetrate through a 40-mesh screen, the smashed wild peach pit shells are soaked in a 60% zinc chloride solution for 24 hours under the condition that the ratio of the wild peach pit shells to the zinc chloride solution is 1:2, then the soaked wild peach pit shells are transferred to a microwave oven with the microwave power ranging from 400W to 700W, and are processed for 10-30 minutes through irradiation, the processed wild peach pit shells are activated for 30-120 minutes at the temperature ranging from 400DEG C to 700DEG C, and then are processed through acid picking in a diluted hydrochloric acid solution which has the volume ratio of being 1:9 and is boiled for 30 minutes, cooling is conducted, the cooled wild peach pit shells are washed until the PH value ranges from six to seven, and are dried, and therefore the wild peach pit shell activated carbon can be obtained. The wild peach pit shell activated carbon made through the method has excellent adsorption performance.
