    Study of the adsorption of methylene blue by natural materials (olive stone, date pit and their mixture) in fixed bed column
    (Aljest, 2019) Abed, F.; Louhab, K.; Abai, Nadjet; Babakhouya, N.
    The present study focuses on the recovery of two agro-food waste available in our country with significant quantities olive pomace and date pits for the removal of a synthetic dye which is methylene blue. Both materials were used in their native forms separated and mixed to improve their adsorptive capacity. A range of physico-chemical analysis was performed to characterize adsorbents used, among them: the FTIR spectroscopy and the scanning electron microscopy. The ability of adsorbents prepared to adsorbe methylene blue (MB) from the aqueous solution was investigated in a fixed bed column. The effects of several important parameters were studied, such as initial concentration of MB, flow rate and bed height. The corresponding breakthrough curves were calculated

    Adsorption of copper (ii) from aqueous solutions on ‎antimony pillar/clay composite
    (Aljest, 2015) Cherifi, H .; Bougherara, S.; Louhab, K.
    The separation of copper from aqueous systems is studied for ‎environmental protection. In this paper was studied the elimination ‎of cooper from dilute aqueous solution by adsorption on a crude ‎and chemical modified clays (pillared layers clays).The kinetics ‎study of the adsorption of copper on the modified clay showed that ‎equilibrium is reached after 60 mn. A high adsorption ‎performance was recorded for the following optimum conditions at ‎the temperature T = 25°C and the solid/liquid ratio = 2, Initial ‎concentration of ion Cu2+ =40 mg /L, the amount of adsorbent ‎clay = 800 mg, pH = 6

    Speciation of chromium in bottom ash obtained by the incineration of the leather waste shavings
    (2006) Louhab, K.; Akssas, H.
    The evolution of bottom ash morphology and chromium metals behavior during incineration of a leather waste shavings at different incineration temperature have been studied. The Cr, Ca, Mg, Cl rates in bottom ashes, flay ashes and emitted gases in different incineration temperature of the tannery wastes are also determined. The morphology of the bottom ashes obtained by incineration at different temperature from the leather waste shavings was examined by MEB. The result show that the temperature and the length of incineration influence on the structure of the bottom ash and on the chromium in the bottom ash
