The pre-concentrated metal cations are directly eluted from the column using 5.0 mL of 1.0 mol L(-1) hydrochloric acid. The optimum pre-concentration conditions are given and the retention efficency achieved is higher than 95%. The enrichment factor is 10 for sample volumes of 50 mL.61-67poradsorptionpre-concentrationoxycellulosePre-concentration of Cd(II), Cr(III), Cu(II) and Ni(II) on a column packed with oxycellulose.ArtigoWOS:A1995TW18100006Acesso restrito
