| 1 | Synthesis of novel adsorbent by intercalation of biopolymer in LDH for the removal of arsenic from synthetic and natural water显示文摘This study focuses on the synthesis of nanocomposites named CCA and CZA that were prepared by the incorporation of cellulose(CL)in the Ca/Al and Zn/Al layered double hydroxide(LDH),respectively.These materials were then used for the uptake of As(Ⅲ)and As(V)from aqueous medium.Characterization of both nanocomposites(CCA and CZA)was done using FTIR and Raman analysis to identify the functional groups,N2 adsorption-desorption isotherms to determine the specific surface area and pore geometry and XPS analysis to obtain the surface atomic composition.Some other characters were investigated using simultaneous TGA and DTA and elemental chemical analysis(CHNS/O).The crystallinity of the prepared nanocomposites was displayed by XRD patterns.Furthermore,the sheet-like structure of the LDHs and the irregularity of surface morphology with porous structure were observed by TEM and SEM microphotographs.Optimization of maximum adsorption capacity was adjusted using different parameters including pH,contact time and adsorbent dosage.The pseudo-second-order model was in good fitting with kinetics results.The adsorption isotherm results showed that CZA exhibits better adsorption capacity for As(Ⅲ)than CCA and the Langmuir isotherm model described the data well for both nanocomposites.Thermodynamic studies illustrated the endothermic nature of CCA and exothermic nature on CZA,as well as the fact that the adsorption process is spontaneous.A real water sample collected from well located in Gabes(Tunisia),has also been treated.The obtained experimental results were confirmed that these sorbents are efficient for the treatment of hazardous toxic species such as. | Hanen Bessaies Sidra Iftekhar Bhairavi Doshi Jamel Kheriji Mohamed Chaker Ncibi Varsha Srivastava Mika Sillanpaa Bechir Hamrouni | 2020 | Journal of Environmental Sciences2020，32，5： | 10 |
| 2 | Characterization and physicochemical aspects of novel cellulose-based layered double hydroxide nanocomposite for removal of antimony and fluoride from aqueous solution显示文摘A series of novel adsorbents composed of cellulose(CL)with Ca/Al layered double hydroxide(CC_(x)A;where x represent the Ca/Al molar ratio)were prepared for the adsorption of antimony(Sb(V))and fluoride(F^(-))ions from aqueous solutions.The CC_(x)A was characterized by Fourier-transform infrared spectroscopy(FTIR),Brunauer–Emmett–Teller(BET),elemental analysis(CHNS/O),thermogravimetric analysis(TGA-DTA),zeta potential,X-ray photoelectron spectroscopy(XPS)and scanning electron microscopy with energy dispersive Xray spectroscopy(SEM-EDX)analysis.The effects of varying parameters such as dose,pH,contact time,temperature and initial concentration on the adsorption process were investigated.According to the obtained results,the adsorption processes were described by a pseudo-second-order kinetic model.Langmuir adsorption isotherm model provided the best fit for the experimental data and was used to describe isotherm constants.The maximum adsorption capacity was found to be 77.2 and 63.1 mg/g for Sb(V)and F^(-),respectively by CC_(3)A(experimental conditions:pH 5.5,time 60 min,dose 15 mg/10 mL,temperature 298 K).The CC_(3)A nanocomposite was able to reduce the Sb(V)and F^(-)ions concentration in synthetic solution to lower than 6μg/L and 1.5 mg/L,respectively,which are maximum contaminant levels of these elements in drinking water according to WHO guidelines. | Hanen Bessaies Sidra Iftekhar Muhammad Bilal Asif Jamel Kheriji Chaker Necibi Mika Sillanpää Bechir Hamrouni | 2021 | Journal of Environmental Sciences2021，33，4： | 4 |
| 3 | Probabilistic analysis of ultimate seismic bearing capacity of strip foundations显示文摘This paper presents a reliability analysis of the pseudo-static seismic bearing capacity of a strip foundation using the limit equilibrium theory. The first-order reliability method(FORM) is employed to calculate the reliability index. The response surface methodology(RSM) is used to assess the Hasofer e Lind reliability index and then it is optimized using a genetic algorithm(GA). The random variables used are the soil shear strength parameters and the seismic coefficients(k_h and k_v). Two assumptions(normal and non-normal distribution) are used for the random variables. The assumption of uncorrelated variables was found to be conservative in comparison to that of negatively correlated soil shear strength parameters. The assumption of non-normal distribution for the random variables can induce a negative effect on the reliability index of the practical range of the seismic bearing capacity. | Adam Hamrouni Badreddine Sbartai Daniel Dias | 2018 | Journal of Rock Mechanics and Geotechnical Engineering2018，10，4： | 3 |

| 10 | Soil spatial variability impact on the behavior of a reinforced earth wall显示文摘This article presents the soil spatial variability effect on the performance of a reinforced earth wall.The serviceability limit state is considered in the analysis.Both cases of isotropic and anisotropic non-normal random fields are implemented for the soil properties.The K arhunen-Loeve expansion method is used for the discretization of the random field.Numerical finite difference models are considered as deterministic models.The Monte Carlo simulation technique is used to obtain the deformation response variability of the reinforced soil retaining wall.The influences of the spatial variability response of the geotechnical system in terms of horizontal facing displacement is presented and discussed.The results obtained show that the spatial variability has an important influence on the facing horizontal displacement as well as on the failure probability. | Adam HAMROUNI Daniel DIAS Badreddine SBARTAI | 2020 | Frontiers of Structural and Civil Engineering2020，14，2： | 1 |
