Abstract
Novel magnetic halloysite‐based molecularly imprinted polymer (MMIP) is fabricated for sunset yellow dye removal from water solution. Field emission scanning electron microscopy, vibrating sample magnetometer, Zeta potential test, thermogravimetric, and nitrogen gas adsorption analysis were all employed for characterizations of the obtained magnetic halloysite and the final adsorbent. Transmission electron microscope images proved the synthesis of polymeric shell onto the magnetic nanotubes with the thickness of 10 nm. The adsorption kinetics were assessed by pseudo‐first order, pseudo‐second order, and intraparticle diffusion models and the results revealed that the obtained MMIP adsorption procedure would be controlled by chemical adsorption due to the high correlation coefficient (R2 ≥ 0.99) achieved for pseudo‐second order model. The effect of dye initial concentration was observed on the …
