Abstract
ENGLISH ABSTRACT: Adsorptive removal of organic pollutant (pyrene) was carried out using coordination polymer [Cu(Pic)2(H2O)2]·H2O (CP-1) (where “Pic” represents picolinic acid), which was prepared from copper acetate monohydrate and picolinic acid. The compound was characterized by spectroscopic techniques, SEM, elemental and thermal analyses and X-ray crystallographic analysis. The crystal structure of CP-1 shows a centrosymmetric triclinic space group P-1 in which a = 5.0924 (4) Å, b = 7.5172 (6) Å, c = 9.0965 (8) Å. The Cu²͘⁺ ion is seen to have an octahedral geometry, which is bonded to oxygen atoms from the picolinic acid and nitrogen atoms from the pyridine rings. Pyrene adsorption from aqueous media was studied with the prepared adsorbent (CP-1). The kinetic model was observed to be second order, and the sorption data fitted best into the Langmuir model. The absorbent, CP-1, was shown to have a 90.91 mg/g adsorption capacity (maximum) for pyrene in this study at 25 °C. Compound CP-1 can thus be presented as a potential adsorbent in the treatment of pyrene-polluted water.
