KINETIC AND EQUILIBRIUM STUDIES ON THE REMOVAL OF Pb (II) FROM AQUEOUS SOLUTION USING NETTLE ASH

In this study the removal of Pb(II) from aqueous solution onto nettle ash (NA) as a low cost adsorbent was reported. Batch mode experiments were conducted at 25 °C to study the effects of initial concentration of lead ions, contact time, pH and adsorbent dose on the removal process. It is observed t...
