The invention belongs to the technical field of adsorbents, and particularly relates to a ketone VOCs adsorbent and a preparation method and application thereof. The adsorbent comprises a zeolite molecular sieve and metal ions; the adsorbent is obtained by carrying out metal ion exchange modification on a zeolite molecular sieve by adopting a metal soluble salt within a specified silica-alumina ratio range; the adsorbent has a suitable silica-alumina ratio, the variety of zeolite molecular sieves, and the variety, number and combination of metal ions. The ketone VOCs adsorbent prepared through the preparation method has the advantages of being high in adsorption rate, good in loading effect and high in selective adsorption capacity on ketone VOCs. The prepared adsorbent is used for adsorbing and purifying the industrial discharged ketone VOCs. 本发明属于吸附剂技术领域，具体涉及一种酮类VOCs吸附剂及其制备方法和应用。所述吸附剂包括沸石分子筛和金属离子；所述吸附剂在指定的硅铝比范围内，采用金属可溶盐对沸石分子筛进行金属离子交换改性得到；所述吸附剂具有合适的硅铝比，沸石分子筛的种类，以及金属离子的种类、数量和组合。所述制备方法制得的酮类VOCs吸附剂具有吸附速率快、负载效果好
