Limited number of studies focuses on fixed bed performance for metal removal. In this study, the removal of Ni 2+ from synthetic wastewater using a strong acidic cation exchange resin in a fixed bed columns was investigated. The experiments were conducted at different pH (3-7) and initial heavy metal concentrations (1.8, 2.8 and 3.8g Ni/L). Investigation of the regeneration effect on the resin was conducted. The removal efficiency and rate of removal are shown on the breakthrough curves and the kinetic study of the process was determined. The Thomas model was applied to follow the exchange dynamics, the results from experimental work were compared to those using Thomas model, it is shown that the calculated breakthrough curves agreed well with the measured ones. The metal level in the treated wastewater was examined using the atomic absorption spectrophotometer to show that the Ni 2+ concentration complies with the standard environmental regulations limits. © 2011 Taiwan Institute of Chemical Engineers. date: 2012 official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-83855160913&doi=10.1016%2fj.jtice.2011.06.006&partnerID=40&md5=326ba44a69e45f0f7c391dbadf0adf83 id_number: 10.1016/j.jtice.2011.06.006 full_text_status: none publication: Journal of the Taiwan Institute of Chemical Engineers volume: 43 number: 1 pagerange: 40-45 refereed: TRUE issn: 18761070 citation: Shaidan, N.H. and Eldemerdash, U. and Awad, S.
