    Microwave assisted preparation of onion skin activated carbon: Application for removal of tetracycline
    (جامعة الوادي - university of el oued, 2021-04-25) Ait Ouaissa, Y; Djbrouni, A; Chabani, S; Chabani, M; Amrane, A; Bensmaili, A
    The activated carbon prepared from onion skin by H2SO4 activation under microwave radiation was investigated. The effect of different condition in order to obtain the high removal efficiency of Tetracycline and carbon yield was studied. The optimum condition has been identified at the acid concentration of 1N, Microwave power of 720W, microwave radiation of 5min and impregnation heating time of 48 h. The obtained activated carbon under these conditions was characterized by scanning electron microscopy and by FTIR spectra. Microwave energy is predicted to be for fuel technology in various areas, while its progress represents an expanding field in the area of adsorption science.

    Study of effect of tin on the electrochemical properties of cycled PbSn alloys of lead-acid battery
    (جامعة الوادي - university of el oued, 2021-01-01) Dilmi, Toufik; Guelil, Abdehamid; Dakhouch, Achour
    Tin has a beneficial effect on the electrochemical properties of the corrosion film formed on PbSn grids by reducing its resistivity mainly on cycling of the battery. Binary alloys with different tin contents were subjected to several charge-discharge cycles between and vs. Electrode in solution at. The electrochemical properties of alloys in sulfuric acid solution were studied by Cyclic Voltammetry, Linear Voltammetry and Chronpotentiometry. The compositions of the corrosion layer obtained at different numbers of cycles were determined by DRX. We were found that reduces the thickness and favorites a more conductive and dense layer between the grid and the positive active mass.
