암모늄티오우레아로 변형된 Walnut 껍질의 합성 및 분석과 수용액에서 납(II) 흡착 특성
Synthesis and Characterization of Aminothiourea Modified Walnut Shell and Its Adsorption for Pb(II) Ions from Aqueous Solution
E-mail:
A novel, green and easy regeneration biosorbent, aminothiourea modified walnut shell (AMWNS), was synthesized, and its potential for removal of Pb(II) ions was also investigated. The AMWNS was synthesized with epichlorohydrin and aminothiourea as an etherifying agent and a modified monomer, respectively, and was characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM) and X-ray diffraction (XRD). The influences of pH (3-11) and adsorbent dosage (0.5-2.5 g/L) on adsorption capacity of AMWNS were investigated. The maximum Pb(II) ions adsorption capacities (Qm) calculated by best fitting model (Langmuir) were 46.25 mg/g at 298 K. Thermodynamic studies demonstrated adsorption process by AMWNS was spontaneous and endothermic. Furthermore, the regeneration capability of AMWNS implied AMWNS was a cheap, excellent biosorbent for Pb(II) ions removal in wastewater treatment.
