Adsorption of Pb 2+ from aqueous solution onto a sugarcane bagasse/multi-walled carbon
nanotube (MWCNT) composite was investigated by using a series of batch adsorption
experiments and compared with the metal uptake ability of sugarcane bagasse. The
efficiency of the adsorption processes was studied experimentally at various pH values,
contact times, adsorbent masses, temperatures and initial Pb 2+ concentrations. A pH of 4.5
was found to be the optimum pH to obtain a maximum adsorption percentage in 120 min of …
