The valen.e of the surface lay.r was an.ly.ed by.X-ray.photo- electron.spectroscopy.(XPS); Three-sweep poten.iody.0}mic polarization.measuremen. was employ.d to value the aqueous corrosion.resistan.e of zircon.um in.a 0.5mol/l h2SO4 solution. It was foun. that a remarkable declin. in.the aqueous corrosion.behavior of zircon.um implan.ed with cerium ion. compared with that of the as-received zircon.um.

As the reaction.product of subducted water an. the iron.core, FeO2with more oxy.en.than.hematite(Fe2O3) has been.recen.ly.recogn.zed as an.importan. compon.n. in.the D" lay.r just above the Earth’s core-man.le boun.ary. here, we report a n.w oxy.en.excess phase(Mg, Fe)2O3+δ(0 n.ted as‘OE-phase’). It forms at pressures greater than.40 gigapascal when.Mg, Fe)-bearin. hy.rous materials are heated over 1500 kelvin. The OE-phase is fully.recoverable to ambien. con.ition. for ex situ in.estigation.usin. tran.mission.electron.microscopy. which in.icates that the OE-phase con.ain. ferric iron.Fe3+) as in.Fe2O3but h.l.s excess oxy.en.through in.eraction. between.oxy.en.atoms. The n.w OE-phase provides stron. eviden.e that h2O has extraordin.ry.oxidation.power at high pressure. Un.ike the formation.of py.ite-ty.e FeO2hxwhich usually.requires saturated water, the OE-phase can.be formed with un.er-saturated water at mid-man.le con.ition., an. is expected to be more ubiquitous at depths greater than.1000 km in.the Earth’s man.le. The emergen.e of oxy.en.excess reservoirs out of primordial or subducted(Mg,Fe)-bearin. hy.rous materials may.revise our view on.the deep-man.le redox chemistry.

Two carboxy.ation.processes were carried out to modify.multi-walled carbon.n.n.t ube bun.les (m-MWn.s). The results showed that both of the m-MWn.s could be high.l. dispersed in.water with the con.en.ration.up to 25 an. 15mg/ml in.ethan.l wit hout obvious deposition.or con.lomeration.over 6 mon.hs.

The results showed that the addition.of m-MWn.s greatly.improved the con.uctivity.an. the thresh.l. of mass fraction.was about 5wt%. The results also proved that purification.process was n.ot n.eded because of high purity.of the raw MWn.s prepared in.our group.

lan.fill leachate treatmen. by.MBR: Performan.e an. molecular weight distribution.of organ.c con.amin.n.

Chin.se Scien.e Bulletin 2006年第23期51卷 2831-2838页

A membran. bioreactor (MBR) with an.air-lift bioreactor an. gravity.flow is applied to treatin. lan.fill leachate. More than.99% of BOD5 (biochemical oxy.en.deman. for five day.) removal effi-cien.y.is achieved with.l.ss than.35 mg/l of BOD_5 in.the effluen. at less than.1.71 kg BOD5/m^3·d of BOD_5 loadin. rate. When.DO (dissolved oxy.en. is main.ain.d at the ran.e of 2.3―2.8 mg/l an. the loadin. rate of n._4^+-n.(ammon.um n.trogen. is kept at 0.16― 0.24 kg n._4^+-n.m^3·d, the n._4^+-n.in.the effluen. is less than.15 mg/l. however, compared with high removal rates of BOD_5 an. n._4^+-n. the removal effi-cien.y.of soluble chemical oxy.en.deman. (SCOD) varies between.70% an. 96%. The in.estigation.of molecular weight (MW) distribution.has been.carried out by.the gel permeation.chromatography.(GPC) so as to un.erstan. the fate of organ.c matters in.the MBR treatin. of lan.fill leachate. Results in.icate that organ.c matters of the lan.fill leachate are composed of a high MW fraction.(MW of the peak, MWp = 11480―13182 Da) an. a low MW fraction.(MWp = 158―275 Da). The high MW fraction.is n.t biode-gradable, but can.be decreased with microfiltration.membran.. The most of the low MW fraction.is bio-degradable, but the residue of the low MW fraction.is able to permeate through the membran., thus re-sultin. in.high SCOD in.the effluen. of the MBR.
