“…K values showed that sawdust is more effective for removing NO 2 -N. Comparing the correlation coefficients in both Langmuir and Freundlich, it was found that Freundlich model (R 2 = 0.8324, 0.9856, and 0.9231 for NH 3 -N, NO 3 -N and NO 2 -N respectively) fits better than Langmuir model (R 2 = 0.7963, 0.9751, and 0.8049 for NH 3 -N, NO 3 -N and NO 2 -N respectively). As the Freundlich type adsorption isotherm is an indication of surface heterogeneity of the adsorbent, this guide us to the conclusion that the surface of sawdust is made from small heterogeneous adsorption patches [24].…”

“…Les sciures naturelles ou traitées chimiquement provenant de différentes espèces d'arbres ont été étudiées pour l'enlèvement de divers métaux en solution dont le cuivre, le cadmium, le plomb, le nickel, le chrome (Cr IM et Cr vl ), le mercure et le zinc. Les recherches ont porté principalement sur les sciures des espèces suivantes : sapin rouge Abies magnifica) (BRYANT ef al., 1992), manga (Mangifera indica) (AJMAL et al, 1996(AJMAL et al, , 1998, tilleul [Tilia americana) (HOLAN et VOLESKY, 1995), épinette {Picea engelmanii) (HOLAN et VOLESKY, 1995), pin (Pinus roxburghii) (CHATTERJEE ef al., 1996), cèdre {Cedrus deodara) (CHATTER-JEE étal., 1996), teck (Teca) (SHUKU\ et SAKHARDANDE, 1990), akamatsu (Pinus desiflora) et buna (Fagas crenata) (MORITA et al, 1987), ainsi que Bassia latifolia (VAISHYA et PRASAD, 1991). Le tableau 2 présente les études répertoriées portant sur l'adsorption des métaux sur des sciures de bois de diverses espèces, ainsi que les principaux paramètres étudiés lors de ces recherches.…”
