TLDR
The results indicates that the highest percentage removal of Pb can be achieved at pH 5, 40 mg/L of CNTs, contact time 80 min, and agitation speed 50 r/min, and the highest correlation coefficients from Langmuir isotherm model indicates the strong adsorptions of P b(II) on the surface of C NTs.
Abstract
The capability of carbon nanotubes (CNTs) to adsorb lead (Pb) in aqueous solution was investigated. Batch mode adsorption experiment was conducted to determine the effects of pH, agitation speed, CNTs dosage and contact time. The removal of Pb(II) reached maximum value 85% or 83% at pH 5 or 40 mg/L of CNTs, respectively. Higher correlation coefficients from Langmuir isotherm model indicates the strong adsorptions of Pb(II) on the surface of CNTs (adsorption capacity Xm = 102.04 mg/g). The results indicates that the highest percentage removal of Pb (96.03%) can be achieved at pH 5, 40 mg/L of CNTs, contact time 80 min, and agitation speed 50 r/min.
