| 2014 | Studies on the removal of Pb (II) from wastewater by activated carbon developed from Apricot stone activated with sulphuric acid Authors L Mouni, L Belkhiri, M Tafer, F Zouggaghe, Y Kadmi Publication date 2014 Journal Moroccan Journal of Chemistry Volume 2 Issue 5 Pages 2-5 (2014) 452-456 Description Studies on the utilization of low cost adsorbents for removal of heavy metals from wastewaters are gaining attention. Activated carbons were developed from Apricot stone, by chemically treating with sulfuric acid. Batch adsorption experiments were performed to find out the effective lead removal at different metal ion concentrations, adsorbent size and dosage. Operational parameters such as pH, agitation time and adsorbent concentration, initial ion concentration and particle size were also studied. Adsorption data fitted well with the Langmuir and Freundlich models. However, Freundlich isotherm displayed a better fitting model than Langmuir isotherm because of the higher correlation coefficient that the former exhibited. Apricot Adsorption kinetics data were modeled using the pseudo-first and pseudo-second-order models. The results indicate that the second-order model best describes adsorption kinetic data. The estimated maximum capacities of lead ions adsorbed by Apricot stone activated with sulphuric acid were 21.38 mg g-1. In addition, the thermodynamic parameters, standard free energy (ΔG 0), standard enthalpy (ΔH 0), standard entropy (ΔS 0) of the adsorption process were calculated | Mouni, Lotfi |

| 2018-07-25 | Assessment of Heavy Metals Contamination in Groundwater: A Case Study of the South of Setif Area, East Algeria Authors Lazhar Belkhiri, Ammar Tiri, Lotfi Mouni Publication date 2018/7/25 Journal Achievements and Challenges of Integrated River Basin Management Pages 17 Publisher BoD–Books on Demand Description Heavy metals in groundwater were analyzed and their sources and impacts were identified using multivariate statistical tools and risk assessment. Three significant factors were extracted by factor analysis (FA), explaining 75.69% of total variance. These factors were in turn described by the clusters C3, C2 and C1, respectively, resulting from the cluster analysis (CA). Factor analysis and cluster analysis revealed significant anthropogenic contributions and water-rock interaction effects of the metals in groundwater. The mean values indicated of heavy that the metal groundwater evaluation samples index (HEI) were and contaminated degree of contamination with high degree (Cdeg of) indices pollution by cadmium (Cd) and lead (Pb). The hazard quotients (via ingestion) of Cd and Pb were found to be higher than the safe limits, posing threat to the consumers. However, no risk related to the dermal contact was associated with the measured metal levels. | Mouni, Lotfi |
