| 520 | |a Activated carbons represent powerful materials for water depollution. In this study, two carbon materials were synthesized by a simple and eco-friendly method using Neem and Hyphaene thebaica biomass waste. The material preparation aimed to reach high surface activity and low cost in order to develop an adsorbent for the removal of harmful substances from water, such as heavy metals. The prepared carbon materials were characterized using various techniques, including Brunauer-Emmett-Teller (BET) specific surface area, thermogravimetric analyses (TGA), inductively coupled plasma-optical emission spectroscopy (ICP-OES) and Fourier transform infrared spectroscopy (FT-IR). The adsorption of Cu (II) ions on activated carbon from Neem (CAN) and Hyphaene thebaica (CAH) hulls was systematically investigated using a batch method by varying several key operational parameters such as contact time, pH, adsorbent dose and the effect of concentration. The results obtained from the study indicated that the maximum uptake capacity was 277 mg/g for CAN and 210 mg/g for CAH at pH 5 after 15 min of equilibrium time in contact with 500 mg/L of initial concentration of copper ions solution. Marczewski-Jaroniec and Sips isotherm models fitted well the experimental data with high R2, adj-R2 and less value or errors analysis for either CAN or CAH. Besides, the kinetic study showed that the adsorption followed a pseudo-first-order model for CAN and a pseudo-second-order for CAH. Thus, this study shows that Neem and Hyphaene thebaica hulls represent a valuable biomass source for the production of activated carbon for heavy metal remediation. | ||

In this study, two carbon materials were synthesized by a simple and eco-friendly method using Neem and Hyphaene thebaica biomass waste. The material preparation aimed to reach high surface activity and low cost in order to develop an adsorbent for the removal of harmful substances from water, such as heavy metals. The prepared carbon materials were characterized using various techniques, including Brunauer-Emmett-Teller (BET) specific surface area, thermogravimetric analyses (TGA), inductively coupled plasma-optical emission spectroscopy (ICP-OES) and Fourier transform infrared spectroscopy (FT-IR). The adsorption of Cu (II) ions on activated carbon from Neem (CAN) and Hyphaene thebaica (CAH) hulls was systematically investigated using a batch method by varying several key operational parameters such as contact time, pH, adsorbent dose and the effect of concentration. The results obtained from the study indicated that the maximum uptake capacity was 277 mg/g for CAN and 210 mg/g for CAH at pH 5 after 15 min of equilibrium time in contact with 500 mg/L of initial concentration of copper ions solution.

Adsorptive efficiency of hull-based activated carbon toward copper ions (Cu |
| abstract |
Activated carbons represent powerful materials for water depollution. In this study, two carbon materials were synthesized by a simple and eco-friendly method using Neem and Hyphaene thebaica biomass waste. The material preparation aimed to reach high surface activity and low cost in order to develop an adsorbent for the removal of harmful substances from water, such as heavy metals. The prepared carbon materials were characterized using various techniques, including Brunauer-Emmett-Teller (BET) specific surface area, thermogravimetric analyses (TGA), inductively coupled plasma-optical emission spectroscopy (ICP-OES) and Fourier transform infrared spectroscopy (FT-IR). The adsorption of Cu (II) ions on activated carbon from Neem (CAN) and Hyphaene thebaica (CAH) hulls was systematically investigated using a batch method by varying several key operational parameters such as contact time, pH, adsorbent dose and the effect of concentration. The results obtained from the study indicated that the maximum uptake capacity was 277 mg/g for CAN and 210 mg/g for CAH at pH 5 after 15 min of equilibrium time in contact with 500 mg/L of initial concentration of copper ions solution. Marczewski-Jaroniec and Sips isotherm models fitted well the experimental data with high R2, adj-R2 and less value or errors analysis for either CAN or CAH. Besides, the kinetic study showed that the adsorption followed a pseudo-first-order model for CAN and a pseudo-second-order for CAH. Thus, this study shows that Neem and Hyphaene thebaica hulls represent a valuable biomass source for the production of activated carbon for heavy metal remediation. |
