Acievments

• Published the article with the title " Picomolar detection of As(III) ions by using hydrothermal synthesis of functionalized polymer dots as a highly selective fluorescence sensor" in Talanta, elsevier, Volume 261, 15 August 2023, 124667, https://doi.org/10.1016/j.talanta.2023.124667

In this paper, a novel water-soluble fluorescent probe based on functionalized polypyrro le dots (FPPyDots) was designed and applied to determine As(III) selectively and sensitively in aqueous media. FPPyDots probe was synthesized by using a hydrothermal method, via the facile chemical polymerization of pyrrole (Py) and cysteamine (Cys) and then functionalized with ditheritheritol (DTT). To investigate the chemical composition, morphology, and optical properties of the resultant fluorescence probe various characterization techniques including FTIR, EDC, TEM, Zeta potential, UV–vis, and fluorescence spectroscopic were used.

• Accepted and ready to publish soon with the title " Novel hybrid ZnS:Mn2+quantum dots/Nmethylpolypyrrole fluorescence probe for determination of nitro-aromatic compounds in water samples by using multivariate chemometric methods" in Journal of the Iranian Chemical Society , Springer

In this paper, a novel ZnS:Mn2+ quantum dots/Nmethylpolypyrrole (ZnS:Mn2+ QDs/NMPPy) hybrid fluorescence probe was synthesised and applied for the simultaneous determination of NACs. Multivariate chemometrics methods, including principal component analysis (PCA) and partial least squares (PLS), were used for processing the collected signals.

" Dispersive solid phase extraction of lead in water samples using embedded 1,5-diphenylcarbazone grafted graphene oxide in microporous magnetic chitosan coupled with flame atomic absorption spectrometry " in Journal of the Iranian Chemical Society, Springer, 16, 1411–1421 (2019), https://doi.org/10.1007/s13738-019-01613-6

In the current study, an embedded 1,5-diphenylcarbazone (DPC) grafted graphene oxide (GO) in porous magnetic chitosan (MC) nanocomposite was synthesized and used for preconcentration of trace amount of Pb(II). For this purpose, a magnetic dispersive solid phase extraction (MDSPE) was utilized prior to determination by flame atomic absorption spectrometry (FAAS). The adsorbent was characterized using Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), transmission electron microscopy (TEM) and vibrating sample magnetometer (VSM).
