In this study, novel magnetic molecularly imprinted polymers (MMIPs) were developed as a sorbent for solid-phase extraction (SPE) and used for the selective separation of metronidazole (MNZ) in cosmetics; MNZ was detected by high-performance liquid chromatography (HPLC). First, magnetic Fe3O4 nanoparticles (NPs) were prepared by the co-precipitation of(More)
Various aluminum phosphates were prepared with phosphoric acid and aluminum hydroxide under different conditions. IR, XRD, Raman and SEM were used to study the structure difference and their change in heating process and particle morphology of obtained products and aluminum tripolyphosphate. The results show that the spectral characteristic change of(More)
In the title compound, [CoCl(C(10)H(7)N(3)S)(2)]Cl·2H(2)O, the Co(II) atom is five-coordinated by four N atoms from two chelating 2-(1,3-thia-zol-4-yl)-1H-benzimidazole ligands and one Cl atom in a distorted trigonal-bipyramidal geometry. In the crystal, N-H⋯O and O-H⋯Cl hydrogen bonds and π-π inter-actions between the thia-zole, imidazole and benzene rings(More)
In the title compound, C(15)H(10)Cl(2)N(4)O(2), the dichloro-pyrimidine and meth-oxy-phen-oxy parts are approximately perpendicular [dihedral angle = 89.9 (9)°]. The dihedral angle between the two pyrimidine rings is 36.3 (4)° In the crystal, there are no hydrogen bonds but the mol-ecules are held together by short inter-molecular C⋯N [3.206 (3) Å] contacts(More)
The Zn atom in the title compound, [Zn(C(7)H(5)O(2))(2)(C(12)H(8)N(2))(H(2)O)], is five-coordinate in a distorted trigonal-bipyramidal coordination environment involving two O atoms of two monodentate benzoates, two N atoms of a 1,10-phenanthroline mol-ecule and one O atom of a water mol-ecule. The axial positions are occupied by a carboxyl-ate O atom from(More)
