| 1 | Synthesis of linear low-density polyethylene-g-poly(acrylic acid)-co-starch/organo-montmorillonite hydrogel composite as an adsorbent for removal of Pb(Ⅱ) from aqueous solutions显示文摘The purpose of this work is to remove Pb(II) from the aqueous solution using a type of hydrogel composite. A hydrogel composite consisting of waste linear low density polyethylene, acrylic acid, starch, and organo-montmorillonite was prepared through emulsion polymerization method. Fourier transform infrared spectroscopy(FTIR), Solid carbon nuclear magnetic resonance spectroscopy(CNMR)), silicon-29 nuclear magnetic resonance spectroscopy(Si NMR)), and X-ray diffraction spectroscope((XRD) were applied to characterize the hydrogel composite. The hydrogel composite was then employed as an adsorbent for the removal of Pb(II) from the aqueous solution. The Pb(II)-loaded hydrogel composite was characterized using Fourier transform infrared spectroscopy(FTIR)),scanning electron microscopy(SEM)), and X-ray photoelectron spectroscopy((XPS)). From XPS results, it was found that the carboxyl and hydroxyl groups of the hydrogel composite participated in the removal of Pb(II). Kinetic studies indicated that the adsorption of Pb(II)followed the pseudo-second-order equation. It was also found that the Langmuir model described the adsorption isotherm better than the Freundlich isotherm. The maximum removal capacity of the hydrogel composite for Pb(II) ions was 430 mg/g. Thus, the waste linear low-density polyethylene-g-poly(acrylic acid)-co-starch/organo-montmorillonite hydrogel composite could be a promising Pb(II) adsorbent. | Maryam Irani Hanafi Ismail Zulkifli Ahmad Maohong Fan | 2015 | Journal of Environmental Sciences2015，27，1： | 11 |
| 2 | Effect of Synthesis Technique and Carbonate Content on the Crystallinity and Morphology of Carbonated Hydroxyapatite显示文摘The syntheses of nanosized carbonated hydroxyapatite(CHA) were performed by comparing dropwise and direct pouring of acetone solution of Ca(N03)2-4H20 into mixture of(NH4)2HP04 and NH4HCO3 at room temperature controlled at pH 11.Direct pouring method was later applied to study the increment of carbonate content in syntheses.The as-synthesized powders were characterized by various characterization techniques.The crystallographic results of the produced powders were obtained from X-ray diffraction analysis,whilst the carbonate content in the produced powders was determined by the CHNS/O elemental analyzer.Fourier transform infrared analysis confirmed that the CHA powders formed were B-type.Field emission scanning electron microscopy revealed that the powders were highly agglomerated in nanosized range and hence energy filtered transmission electron microscopy was employed to show elongated particles which decreased with increasing carbonate content. | Chia Ching Kee Hanafi Ismail Ahmad Fauzi Mohd Noor | 2013 | Journal of Materials Science & Technology2013，29，8： | 5 |

| 20 | ANN approaches to determine the dielectric strength improvement of MgO based low density polyethylene nanocomposite显示文摘This paper presents the modification occurred to the dielectric strength feature of low density polyethylene compounded with nano magnesia(LDPE/MgO).MgO nanoparticles were prepared using sol-gel technique,MgO filler surface was functionalized to improve the interfacial bonding.Specimen’s groups of composites with different filler concentrations were fabricated by mix blend method.Samples exposed to various salinity media by immersion,dielectric strength test was applied on each set according to relevant ASTM standard with identical testing technique.The results were statistically processed then compared to the pristine material.Tests results utilized to learn Artificial Neural Network in order to acquire the value of dielectric strength of compounds having similar composition but containing different doping amounts or influenced with various salinity level media.The dielectric strength is enhanced by the addition of MgO nanofiller.From the investigation of the obtained results,it is concluded that additives of 1.4%filler concentration by weight is the optimum MgO content for LDPE/MgO nanofiller material.We think that this paper may promote a good researching methodology that gather both empirical work and numerical tools in this field. | Sherif Haggag Loai Nasrat Hanafy Ismail | 2021 | Journal of Advanced Dielectrics2021，11，4： | 0 |
