Zin. an. cadmium pollutan.s cause a sign.fican. en.iron.en.al effect that can.ot be ign.red. Due to their con.iderable amoun. in.an.aqueous en.iron.en., in.ustries are seekin. suitable adsorben.s that are en.iron.en.ally frien.ly an. in.xpen.ive for removin. metals from wastewater before disposin. of them in.surface waters. This research employed origin.l MXen.(MX) an. chitosan.modified MXen.(CsMX) to extract zin.(Zn.Ⅱ)) an. cadmium(Cd(Ⅱ)) metal ion. from water-based solution.. The composite material produced was an.lyzed usin. techn.ques such as X-ray Diffraction.XRD), scan.in. Electron.Microscopy(sEM), Fourier Tran.form In.rared spectroscopy(FTIR), an. Brun.uer-Emmett-Teller(BET). The effects of con.act duration. p H of the solution. an. in.tial con.en.ration.of metal ion. on.the adsorption.process of Zn.Ⅱ) an. Cd(Ⅱ) on.o both MX an. CsMX composites were in.estigated. MX an. prepared CsMX composite presen.ed a high adsorption.capacity for both studied heavy metals, which were 91.55 an. 73.82 mg/g for Zn.Ⅱ) an. Cd(Ⅱ) on.o MX, 106.84 an. 93.07 mg/g for Cd(Ⅱ) an. Zn.Ⅱ) on.o CsMX composite, respectively. Furthermore, the maximum competitive adsorption.capacities for Zn.Ⅱ) on.o MX an. CsMX composites are 77.29 an. 93.47 mg/g, an. for are Cd(Ⅱ)60.30 an. 79.66 mg/g, respectively. Hen.e, the removal capacities for both sin.le an. competitive metal ion. were superior to CsMX composite. However, the adsorption.capacities after five successive regen.ration.sequen.es were on.y dropped by 13.2% for Zn.Ⅱ) an. 17.4% for Cd(Ⅱ) on.o the CsMX composite compared to the first cycle. These results con.irm that both metals could be efficien.ly termin.ted from wastewater, which makes the prepared CsMX composite a favorable can.idate adsorben. in.practical application..
