The phenol imprinted polymer is prepared by a mass polymerization method by utilizing a molecular imprinting technology, and the obtained adsorbent has loose and porous surface and contains a large number of holes with structures and shapes matched with phenol molecules, so that the phenol imprinted polymer has high selectivity. The adsorbent is added into the ternary composite filter tip, and the addition amount of the adsorbent can be adjusted randomly according to requirements. When the amount of the phenol added was 10 mg/liter, the decrease rate of phenol was 17.8% and the decrease rate of selectivity to tar was 11.8% as compared with the control, and when the amount of the phenol added was 20 mg/liter, the decrease rate of phenol was 28.7% and the decrease rate of selectivity to tar was 12.3% as compared with the control. The method is simple to operate, low in cost and convenient for large-scale industrial production.
