Data for: Citric acid-modified potato peel waste for the removal of lead(II) from aqueous solutions

Description

Underlying data supporting the manuscript 'Citric acid-modified potato peel waste for the removal of lead(II) from aqueous solutions'. The dataset includes the following experimental data: 1. FTIR spectra of PPW, Na-PPW, CA-PPW, and CA-PPW-Pb (Figure 1). 2. Effect of process parameters on the adsorption capacity (qe or qt) and removal efficiency (%R) of Pb(II) by CA-PPW: adsorbent dose, initial Pb(II) concentration, solution pH, and contact time (Figure 3). 3. Langmuir and Freundlich equilibrium isotherm modeling and the corresponding Langmuir separation factor (RL) for Pb(II) adsorption onto CA-PPW (Figure 4). 4. Pseudo-first-order and pseudo-second-order kinetic modeling for Pb(II) adsorption onto CA-PPW (Figure 5).
