The ZnO:Pb (2 and 4%) nanoparticles have been characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy, scanning electron microscopy, energy dispersive X-ray spectroscopy and cryogenic nitrogen adsorption method. The average size of the synthesized nanoparticles was less than 100 nm and the surface areas were 18.8 and 20.8 m2\/g, respectively for ZnO:Pb 2% and ZnO:Pb 4%. Batch sorption experiments were performed for color removal of RB5 dye at ambient temperature and 30 mg\/L dye concentration. The central composite design with response surface methodology was used to study the effect of sorption condition (pH, nanoparticles dose and contact time). The significance of independent variables and their interactions was tested by analysis of variance. The optimum conditions of color removal were pH = 7, 2 g\/L dose of nanoparticles and a contact time of 79 min. The color removal performance was 79.4 and 98.1% for ZnO:Pb 2 and 4% respectively. The pseudo-second-order model described well the removal rates while the Langmuir model fitted well the adsorption isotherms.<\/jats:p>","DOI":"10.2166\/wst.2020.501","type":"journal-article","created":{"date-parts":[[2020,10,18]],"date-time":"2020-10-18T10:52:07Z","timestamp":1603018327000},"page":"2576-2591","update-policy":"https:\/\/doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":19,"title":["Pb doped ZnO nanoparticles for the sorption of Reactive Black 5 textile azo dye"],"prefix":"10.2166","volume":"82","author":[{"given":"Roua","family":"Ben Dassi","sequence":"first","affiliation":[{"name":"Laboratory of Treatment and Valorization of Water Reject, CERTE, Ecopark of Borj-Cedria, 2080 Soliman, Tunisia"},{"name":"Faculty of Sciences of Bizerte, University of Carthage, 7021 Jarzouna, Tunisia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Baha","family":"Chamam","sequence":"additional","affiliation":[{"name":"Laboratory of Treatment and Valorization of Water Reject, CERTE, Ecopark of Borj-Cedria, 2080 Soliman, Tunisia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean Pierre","family":"M\u00e9ricq","sequence":"additional","affiliation":[{"name":"Institut Europ\u00e9en des Membranes, IEM, UMR 5635, ENSCM, CNRS, Univ Montpellier, Montpellier, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marc","family":"Heran","sequence":"additional","affiliation":[{"name":"Institut Europ\u00e9en des Membranes, IEM, UMR 5635, ENSCM, CNRS, Univ Montpellier, Montpellier, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Catherine","family":"Faur","sequence":"additional","affiliation":[{"name":"Institut Europ\u00e9en des Membranes, IEM, UMR 5635, ENSCM, CNRS, Univ Montpellier, Montpellier, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lassaad","family":"El Mir","sequence":"additional","affiliation":[{"name":"Laboratory of Physics of Materials and Nanomaterials Applied at Environment, Gabes University, Faculty of Sciences of Gabes, 6072, Gabes, Tunisia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chedly","family":"Tizaoui","sequence":"additional","affiliation":[{"name":"College of Engineering, Swansea University, Bay Campus, Fabian Way, Swansea SA1 8EN, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ismail","family":"Trabelsi","sequence":"additional","affiliation":[{"name":"Laboratory of Treatment and Valorization of Water Reject, CERTE, Ecopark of Borj-Cedria, 2080 Soliman, Tunisia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"945","published-online":{"date-parts":[[2020,10,17]]},"reference":[{"key":"key-10.2166\/wst.2020.501-1","doi-asserted-by":"publisher","DOI":"10.1080\/19443994.2014.895778"},{"issue":"2","key":"key-10.2166\/wst.2020.501-2","first-page":"113","article-title":"Incorporation of Pb2+, Fe2+ and Cd2+ ions in ZnO nanocatalyst for photocatalytic activity","volume":"8","author":"Bordbar","year":"2018","journal-title":"Iranian Journal of Catalysis"},{"key":"key-10.2166\/wst.2020.501-3","doi-asserted-by":"publisher","DOI":"10.1007\/s12039-013-0396-8"},{"key":"key-10.2166\/wst.2020.501-4","doi-asserted-by":"publisher","DOI":"10.1016\/j.jenvman.2018.07.021"},{"key":"key-10.2166\/wst.2020.501-5","doi-asserted-by":"publisher","DOI":"10.1007\/s10311-018-0785-9"},{"key":"key-10.2166\/wst.2020.501-6","first-page":"295","article-title":"Combination of coagulation-flocculation and adsorption on granular activated carbon for color removal from AR18 and real textile wastewater","volume":"19","author":"Dassi","year":"2017","journal-title":"Journal of the Tunisian Chemical Society"},{"key":"key-10.2166\/wst.2020.501-7","doi-asserted-by":"publisher","DOI":"10.1016\/j.jiec.2018.12.050"},{"key":"key-10.2166\/wst.2020.501-8","unstructured":"Dubinin M.
