A new bodipy/pillar[5]arene functionalized magnetic sporopollenin for the detection of Cu(II) and Hg(II) ions in aqueous solution.

[Display omitted] • The environmentally friendly magnetic MS-Sp-P [5] -bodipy microcapsule sensor has successfully synthesized for the selective and sensitive detection of Cu(II) and Hg(II) ions in aqueous media. • The magnetic MS-Sp-P [5] -bodipy microcapsule sensor surface was characterized by several techniques such as FT-IR, SEM, XRD. • The photophysical measurements were fluorometrically performed for the detection of Hg(II) and Cu(II) ions in the fluorescence spectroscopy that the limit of detection is 0.06 µM and 2.27 µM. respectively. In this study, a new bodipy/pillar[5]arene functionalized magnetic MS-Sp-P[5]-bodipy microcapsule sensor was prepared based on the use of environmentally friendly for the selective and sensitive detection of Cu(II) and Hg(II) ions in aqueous media. SEM results used in the characterization process of the materials synthesized at each stage confirmed the structural and morphological changes in the pore structure, while other characterization results (FT-IR and XRD) elucidated the role of pillar[5]arene compound and bodipy dye in the synthesis of magnetic microcapsule sensors. The colloidal solution of MS-Sp-P[5]-bodipy (water/ethanol)) showed two fluorescence bands centered at 402 and 540 nm. The detection limits of MS-Sp-P[5]-bodipy for Hg(II) and Cu(II) were calculated to be 0.06 µM and 2.27 µM, respectively (at 540 nm). The linear range of the magnetic sensor for Hg(II) and Cu(II) was found to be in the range of 1–150 µM and 10–150 µM, respectively. The experimental results (response time, pH, temperature, sensitivity and selectivity) demonstrated the applicability and potential of the prepared magnetic microcapsule sensor for the detection of Cu(II) and Hg(II) in water and tap water samples containing heavy metal ions.
