Study on Amino-functionalized Porous Carbon Materials for MB and Cr(VI) Adsorption
نویسندگان
چکیده
From the perspective of environmental protection, high removal rate, reusable and degradable, amino-functionalized porous hydrogel material P-(EA-β-CD/KHA/AC) was synthesized by introducing ethylamino cyclodextrin, humic acid, activated carbon, using polyacrylic acid as carrier. MB Cr (VI) are common wastewater pollutants, thus, Such contaminants must be removed from water. The gel materials before after adsorption were characterized Fourier transform infrared spectroscopy, X-ray diffraction, photoelectron spectroscopy. Cr(VI) showed capacity. At 298 K pH 8, capacities for 262.31 170.12 mg/g, respectively, rates 98.96% 70.27%, respectively. behavior follows pseudo-second-order kinetic equation, conforming to Langmuir model; through intermolecular forces, π–π conjugation, chelation, other interactions, entropy-increasing, endothermic, spontaneous process is formed. regeneration degradability experiments conducted its recycling performance verified.

Thermodynamic equations are de®eloped for adsorption of multicomponent gas mixtures in microporous adsorbents based on the principles of solution thermodynamics. The con®entional spreading pressure and surface area ®ariables, which describe 2-D films, must be abandoned for adsorption in micropores, in which spreading pressure cannot be measured experimentally or calculated from intermolecular f...
