Molecular imprinting technology (MIT) utilizes molecularly imprinted polymers (MIPs) to create highly selective adsorbents with tailored binding sites. This study focuses on developing methylene blue (MB) adsorbents using MIPs synthesized via photopolymerization. The optimal adsorption capacity was achieved with a monomer-to-crosslinker ratio of methacrylic acid (MAA) to ethylene glycol dimethacrylate (EGDMA) at 1:20 mol. The MIPs demonstrated efficient adsorption with extraction and re-extraction times of 40 and 60 minutes, respectively, and an optimal pH of 4.0, resulting in an adsorption capacity of 787.74 mg/g. The MIPs offer advantages for MB adsorbents, such as simplicity, stability, and reusability, distinguishing them from traditional adsorbents, such as activated carbon, due to their superior selectivity. © 2025, Rasayan Journal of Chemistry, c/o Dr. Pratima Sharma.
