Synthesis of zeolite Na-P1 from coal fly ash produced by gasification and its application as adsorbentfor removal of Cr(VI) from water

Yixin Zhang, Lu Zhou, Liqing Chen, Yang Guo, Fanhui Guo, Jianjun Wu, Baiqian Dai

Frontiers of Chemical Science and Engineering 2021, Volume 15, Issue 3,   Pages 518-527 doi: 10.1007/s11705-020-1926-9

Abstract: The coal fly ash produced by gasification is estimated to be over 80 million ton per year in China by 2021. It has mainly been disposed as solid waste by landfill. There is lack of study focused on its utilization. In this paper, the coal fly ash produced by gasification was at first analyzed and then applied to synthesize zeolite as an adsorbent. The effects of synthesis conditions on the cation exchange capacity (CEC) of zeolite were investigated. The results from X-ray diffraction and scanning electron microscope indicated that the crystallinity of the synthesized zeolite is the most important factor to affect the CEC. When the synthesized zeolite with the highest CEC (275.5 meq/100 g) was used for the adsorption of Cr(VI) from aqueous solution, the maximum adsorption capacity for Cr(VI) was found to be 17.924 mg/g. The effects of pH, contact time and initial concentration on the adsorption of Cr(VI) were also investigated. The adsorption kinetics and isotherms can be well described by the pseudo-second-order model and Langmuir isotherm model, respectively.

Strengthening of polysulfone membranes using hybrid mixtures of micro- and nano-scale modifiers

Peyman P. Selakjani, Majid Peyravi, Mohsen Jahanshahi, Hamzeh Hoseinpour, Ali S.

Frontiers of Chemical Science and Engineering 2018, Volume 12, Issue 1,   Pages 174-183 doi: 10.1007/s11705-017-1670-y

Abstract: Polysulfone (PSf) membranes were modified by either a new organic modifier (sulfonated poly(ether sulfide sulfone), SPESS) or a traditional modifier (rice hulk). These membranes were further reinforced with either multi-walled carbon nanotubes (MWCNTs) or silica nanoparticles. Having a dye rejection of 98.46%, the reinforced membranes increased more than 50% in strength but no change in solution flux was observed. The morphological and roughness studies were conducted using scanning electron microscopy and atomic force microscopy. Moreover, the PSF membranes were also characterized by differential scanning calorimetry. Modifying the membranes with organic modifier or nanofiller increases the glass transition temperature ( ). The highest and strength were observed for the PSf-SPESS-MWCNT membrane. SPESS decreases surface roughness but MWCNT increases roughness on the nanoscale. All membranes show a bimodal pore size distribution, whereas the PSf-SPESS-MWCNT membrane exhibits a relatively uniform distribution of macroscopic and microscopic pores.
