Effective recovery of UO

from wastewater is essential for nuclear fuel industry and related industries.In this study

a novel adsorbent was prepared by loading titanium(Ti

4+

) onto collagen fiber(TICF)

and its physical and chemical properties as well as adsorption to UO

2

2+

in nuclear fuel industrial wastewater were investigated.It is found that TICF can effectively recover UO

2

2+

from the wastewater with excellent adsorption capacity.The adsorption capacity is 0.62 mmol·g

-1

at 303 K and pH 5.0 when the initial concentration of UO

2

2+

is 1.50 mmol·L

-1

.The adsorption isotherms can be described by the Langmuir equation and the adsorption capacity increases with temperature.The effect of co-existed F on the adsorption capacity for UO

2

2+

is significant

which can be eliminated by adding aluminum ions as complexing agent

while the other co-existed ions in the solutions

including HCO

Cl

NO

Ca

2+

Mg

2+

and Cu

2+

have little effect on the adsorption capacity for UO

2

2+

.The saturated TICF after UO

2

2+

adsorption can be regenerated by using 0.2 mol·L

-1

nitrate(

) as desorption agent

and the TICF can be reused at least three times.Thus the TICF is a new and effective adsorbent for the recov

ery of UO

2

2+

from the wastewater.
