[0020] Example 1
[0021] A method for preparing porous cellulose acetate microsphere adsorbent specifically includes the following steps:
[0022] Step 1. Extract the cellulose acetate in the filter by Soxhlet extraction method: collect 100 cigarette butts, remove the remaining shredded tobacco in the cigarette butts, cut the fiber rod wrapping paper with a blade, and take out the fiber rod (remove the burnt fiber rod), Obtain 20 grams of fiber rods; divide the fiber rods into several times, wrap the fiber rods with filter paper, put them into the leaching column of the Soxhlet apparatus, add 100 mL of 95% industrial ethanol to the distillation flask, connect to the condenser, and heat to reflux on the heating mantle. The reaction temperature of reflux is 100℃, and the immersion extraction is carried out. Observe the color of ethanol in the overflow tube. When the color of the ethanol turns from dark yellow to colorless, stop the reaction, which takes about 2-3 hours; take out the...
