“…As Table 3 shows, most often HCl solutions are applied for the recovery of metal ions, however the concentrations recommended vary within a wide range, from 1 mmol dm À 3 to 1 mol dm À 3 (Geay et al, 2000;Liu et al, 2001Liu et al, , 2002Güc -lü et al, 2003;Zhou et al, 2004). Othman et al (2009) used concentrations up to 5 mol dm À 3 , however, at high concentrations hydrolysis of cellulose must be considered.…”

“…Details on the preparation of efficient grafted biosorbents and their effects on the metal binding capacity are outlined by O'Connell et al [170]. In a typical example, Grey et al [210] developed an efficient biosorbent via succinic anhydride grafted wood pulp which showed a biosorption capacity of 169 mg/g for Cd(II). Wood sawdust was grafted via acrylonitrile and hydroxylamine and the resulting biosorbents brought about a binding capacity of 246 mg/g for Cu(II) and 188 mg/g for Ni(II) respectively [211].…”

“…In particular, wood derivatives are considered to be highly effective adsorbents (Geay et al, 2000). The original natural material is usually modified by a thermal process that leads to the development of a microporous structure.…”
