Lignocellulosic materials are one of the most common adsorbents
since they are raw materials available in large quantities that
can be by-products of industrial processes [8,9].Amongthese materials,
sugarcane bagasse [6,7,10–17] and wood sawdust [7,18–20],
are attractive options and their use as sorbents may be a benefit
to the environment reducing agricultural wastes since they might
be converted into cheap adsorbents replacing the traditional synthetic
resins [21]. The use of various adsorbents for this purpose has
recently been reported by some researchers to remove zinc from
aqueous solutions or from wastewater
