Dinitro-ortho-cresol (DNOC) is a pesticide compound commonly used as herbicides, larvacides, and insecticides in agriculture. DNOC is a toxic compound when exposed to humans and it can cause nausea, stomach disorders, anxiety, excessive burning, etc. It is of great significance to remove DNOC from the environment. In  this  study,  the  effective  method  for  the  preparation  of imprinted by molecular system has been carried out. The benefit of this method is easy for preparation, stable, repeatable use,  high mechanical strength, and resistance to heat and pressure. The objective of this research is to synthesize and characterize the functional material (MIP) that can be used for sorbent  material of solid phase extraction (SPE). MIP for DNOC was prepared using methacrylic acid (MAA) as a functional monomer, ethylene glycol dimethacrylate (EGDMA) as a crosslinker, benzoyl peroxide (BPO) as an initiator, and acetonitrile as a porogen. The morphous, composition,  structure  and performance of polymer adsorbent was characterized by FT-IR, SEM, and TGA. The results shows  the polymer adsorbent was prepared, successfully. This material had a good binding properties and less waste so it was accordance with the concept of green analytical chemistry. The material was suggested for application  in separation of DNOC from other compounds in environmental matrix sample.
