Without pretreatment or activation, the adsorbents were used to treat real textile wastewater samples (collected from Fez city, Morocco). As a cost-effective alternative, these materials were characterized by different analyses, including X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and X-ray fluorescence (XRF). Chemical oxygen demand (COD) and biological oxygen demand (BOD) were used to characterize the textile wastewater. Additionally, the influence of operating conditions (contact time, adsorbent dosages, and pH) was evaluated. Results show that the adsorption process takes place quickly, reaching the equilibrium at 90 and 160\u2009min for M1 (88% COD) and M2 (79% COD). Both materials show a higher affinity to Cr (39%) and lower affinity to Cu (28%). A pseudo-second-order kinetic model provides the best fit to the experimental adsorption data. Germination tests indicate a low toxicity after the adsorption process. Performance of both materials was compared with that of other literature studies.<\/jats:p>","DOI":"10.1155\/2020\/6457825","type":"journal-article","created":{"date-parts":[[2020,8,13]],"date-time":"2020-08-13T23:36:10Z","timestamp":1597361770000},"page":"1-13","source":"Crossref","is-referenced-by-count":38,"title":["Adsorption Studies on the Removal of Textile Effluent over Two Natural Eco-Friendly Adsorbents"],"prefix":"10.1155","volume":"2020","author":[{"given":"Ouissal","family":"Assila","sequence":"first","affiliation":[{"name":"Laboratory of Catalysis, Materials and Environment, Higher School of Technology, Sidi Mohamed Ben Abdellah University of Fez, 30000 Fez, Morocco"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8393-4479","authenticated-orcid":true,"given":"Karim","family":"Tanji","sequence":"additional","affiliation":[{"name":"Laboratory of Catalysis, Materials and Environment, Higher School of Technology, Sidi Mohamed Ben Abdellah University of Fez, 30000 Fez, Morocco"}]},{"given":"Morad","family":"Zouheir","sequence":"additional","affiliation":[{"name":"Laboratory of Catalysis, Materials and Environment, Higher School of Technology, Sidi Mohamed Ben Abdellah University of Fez, 30000 Fez, Morocco"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5619-8819","authenticated-orcid":true,"given":"Abdellah","family":"Arrahli","sequence":"additional","affiliation":[{"name":"Euromed Research Center, National Institute of Applied Sciences, Euro-Mediterranean University of Fez, Morocco"}]},{"given":"Loubna","family":"Nahali","sequence":"additional","affiliation":[{"name":"Laboratory of Catalysis, Materials and Environment, Higher School of Technology, Sidi Mohamed Ben Abdellah University of Fez, 30000 Fez, Morocco"}]},{"given":"Farid","family":"Zerrouq","sequence":"additional","affiliation":[{"name":"Laboratory of Catalysis, Materials and Environment, Higher School of Technology, Sidi Mohamed Ben Abdellah University of Fez, 30000 Fez, Morocco"}]},{"given":"Abdelhak","family":"Kherbeche","sequence":"additional","affiliation":[{"name":"Laboratory of Catalysis, Materials and Environment, Higher School of Technology, Sidi Mohamed Ben Abdellah University of Fez, 30000 Fez, Morocco"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1007\/s10311-003-0039-2"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/0927-7757(95)03280-8"},{"key":"3","doi-asserted-by":"crossref","first-page":"321","DOI":"10.2166\/wst.2000.0531","article-title":"Reactive textile dye colour removal in a sequencing batch reactor","volume":"42","author":"N.
