Preparation of octylphenol ethoxylate adsorbing material

Preparation of an octylphenol ethoxylate adsorbing material comprises the steps of pumping pure water and a polymerization inhibitor into a reaction still, adding a certain amount of dispersant, an initiator, chitosan, 4-bromo-B,B-difluoro styrene, porphyrin acrylate and docosyl polyoxyethylene ether methacrylate, raising the temperature until a reaction temperature is obtained, and reacting, wherein after the reaction is completed, a surface modified adsorbent containing polyoxyethylene ether groups is obtained.
