In order to remove heavy metal ions from soil and reduce the harm of heavy metals to the environment, modified peanut shell was used to adsorb Cr<jats:sup>3+<\/jats:sup> in this article. The effects of different adsorption conditions on the adsorption rate and adsorption capacity of Cr<jats:sup>3+<\/jats:sup> on ZnCl<jats:sub>2<\/jats:sub> modified peanut shell were studied, the best adsorption conditions were explored, and the relationship of kinetics, thermodynamics and adsorption isotherm properties of adsorption process were explored. The results showed that the optimum adsorption pH value, dosage, initial concentration, adsorption temperature and contact time of ZnCl<jats:sub>2<\/jats:sub> modified peanut shell were 2.5, 2.5\u2005g\/L, 75\u2005\u03bcg\/mL, 25\u2009\u00b0C and 40\u2005min, respectively. The prepared materials were characterized and analyzed by scanning electron microscope (SEM) and X\u2010ray diffraction (XRD) analyzer. It was concluded that the modified peanut shell had a good adsorption capacity to Cr<jats:sup>3+<\/jats:sup>. The kinetic study showed that the adsorption process of Cr<jats:sup>3+<\/jats:sup> on peanut shell modified by zinc chloride was in accordance with the quasi\u2010second\u2010order kinetic model. The adsorption process belonged to exothermic reaction and belonged to spontaneous reaction process. In summary, it is proved that zinc chloride modified peanut shell can efficiently adsorb Cr<jats:sup>3+<\/jats:sup>, which can be used for the treatment of heavy metal wastes in industry, which is beneficial to environmental protection and avoid heavy metal pollution.<\/jats:p>","DOI":"10.1002\/cbdv.202201095","type":"journal-article","created":{"date-parts":[[2023,4,7]],"date-time":"2023-04-07T08:38:38Z","timestamp":1680856718000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Study on the Adsorption of Cr<sup>3+<\/sup> by Peanut Shell: Adsorption Kinetics, Thermodynamics, and Isotherm Properties"],"prefix":"10.1002","volume":"20","author":[{"given":"Xiao\u2010Dong","family":"Li","sequence":"first","affiliation":[{"name":"Department of Basic Science Jilin Jianzhu University, 5088 Xincheng Street  Changchun 130118, Jilin Province P.
