Abstract

In this research, a new nanomagnetic molecularly imprinted polymer (nanoMMIP) of brilliant blue FCF (BB) with high-efficiency and nanomagnetic non-imprinted polymer (nanoMNIP) were synthesized by a simple method in water medium as a green solvent. Acryl amide and N,N′-methylene-bis-acrylamide were used as the functional monomer andcross linking agent, respectively. The synthesized nanoMMIP and nano MNIP were characterized using thermal gravimetric analysis (TGA), transmissionelectron microscopy (TEM), scanning electron microscopy(SEM), and Fouriertransforminfrared spectroscopy (FT-IR). The nano MMIP,as a selective sorbent,was used to extract BB from real samples. The effect of pH, time and BB concentrationin addition toadsorption isothermswere studied. The imprinting-induced extraction was confirmed by determination of recovery values for nano MNIP (37%) and nano MMIP (90%). The maximum binding capacity of nano MMIP for this template was 3.25 mg/g. © 2018, The Polymer Society, Taipei.
