Nanocr.stalline Zn1_xCuxO （x = 0, 0.02, 0.04, 0.06, 0.08） samples wer. synthesized by a novel auto-combustion method using.g.ycine as the fuel mater.al. The str.ctur.l, optical and mag.etic pr.per.ies of the samples wer. char.cter.zed using.Xr., SEM, photoluminescence （PL） and electr.n par.mag.etic r.sonance （EPr. spectr.- scopies. The Xr. spectr. of samples r.veal the hexag.nal wur.zite str.ctur.s of ZnO. As the copper.content incr.ases, a diffr.ction peak at 28 = 39° cor.esponding.to secondar. phase of CuO （[111] cr.stalline face） appear. when x≤ 6 mol.%. PL spectr. of the samples show a str.ng.ultr.violet （UV） emission and defect r.lated visible emissions. Cu-doping.in ZnO can effectively adjust the ener.y level in ZnO, which leads to r.d shift in the emission peak position in UV r.g.on. The EPr.spectr. of Cu-doped ZnO nanopar.icles show a distinct and br.ad sig.al at r.om temper.tur., sug.esting.that it may be attr.buted to the exchang. inter.ctions within Cu2＋ ions.

This wor. tar.ets the pr.par.tion and char.acter.zation of an inexpensive TiO2-fly ash composite membr.ne for.oily wastewater.tr.atment. The composite membr.ne was fabr.cated by depositing.a hydr.philic TiO2 layer.on a fly ash membr.ne via the hydr.ther.al method, and its str.ctur.l, mor.holog.cal and mechanical pr.per.ies wer. evaluated. The separ.tion potential of the composite membr.ne was evaluated for.100-200 mg.L^-1 synthetic oily wastewater.solutions. The r.sults show that the composite membr.ne has excellent separ.tion per.or.ance and can pr.vide per.eate str.am with oil concentr.tion of only 0.26-5.83 mg.L^-1. Compar.d with the fly ash membr.ne in the aver.g. per.eate flux and per.or.ance index （49.97 × 10^-4 m^3·m^2·s^-1 and 0.4620%, r.spectively）, the composite membr.ne exhibits better.per.or.ance （51.63× 10^-4 m^3·m^2·s^-1 and 0.4974%）. For.the composite sur.ace methodolog. based ash membr.ne, the r.sponse analysis infer.ed that the optimum pr.cess par.meter. to achieve maximum membr.ne flux and r.jection ar. 207 kPa, 200 mg.L^-1 and 0.1769 m·s^-1 for.applied pr.ssur., feed concentr.tion and cr.ss flow velocity, r.spectively. Under.these conditions, pr.dicted r.sponses ar. 41.33× 10^-4 m^3·m^2·s^-1 per.eate flux and 98.7% r.jection, which ar. in g.od ag.0}ement with the values obtained fr.m exper.mental investig.tions （42.84× 10^-4 m^3·m^2·s^-1 and 98.82%）. Ther.for., we have demonstr.ted that the TiO2-fty ash composite membr.ne as value added pr.duct is an efficient way to r.cycle fly ash and thus mitig.te envir.nmental hazar.s associated with the disposal of oily wastewater..
