Experimental study on the treatment of uranium-contaminated mine wastewater using zero-valent iron nanoparticles Tugui Yuan1,a ,Diyun Chen1,b 1School of Environmental Science and Engineering, Guangzhou University, Guangzhou ,Guangdong,510006,China ayuantugui@163.com ,bcdy@gzhu.edu.cn Keywords: iron ,nanoparticles, uranium,treatment ,zero-valen Abstract Zero-valent iron nanoparticles( nano-Fe0) were applied as a treatment tactics for a uranium-containing mine wastewater taken from Shaoguan, Guangdong, China.
Different factors including pH value, nano-Fe0 dosage,reaction time were introduced to study the effect posed by those factors.Results indicated that those factors have significant effect on uranium removal rate.The best removal effect happened when pH=5~6, nano-Fe0 iron dosage is 2g/l,reaction time is 1h.It is also demonstrated that nano-Fe0may be an effective material for treatment of complex uranium-contaminated effluent. 1.

Tilt-up process can reduce the cost of labor and materials in wall construction.
Then, the transportation of the material are also reduced.
So the pollution from the cars which transit the material can be reduced, too.

Because of this property, denser materials like steels, cast iron and copper based alloys and even aluminum alloys are being replaced with magnesium alloys.
Therefore, a greater attention is focused on magnesium alloys as structural materials and load bearing parts in vehicles [1].

(2) Thermal spray technology: The raw materials are heated up to gas, and form film by spraying on sample surface at high speed.
The differences of these techniques mainly focus on deposition rate, substrate temperature, suspension materials, equipments, cost and properties.
CVD, SP, TST, PLD, EPD, sol-gel, centrifugal casting and screen printing all need bottom materials, whereas tape casting and tape calendar need not.

Construction work consumes a large amount of wood materials, and global wood products manufacturing totals about 900 tons per year [1].
To counter these concerns, attempts have been made to develop novel polymeric adhesives from new source materials such as natural rubber (NR).
However, wood materials contain a variety of highly polar ingredients, including cellulose and lignin, and polar adhesives are more suitable for wood products.

According to Von Mises, the principles of yielding and the associated rules of plasticity flowing, it is concluded that the material will have plastic displacement and the direction of plastic strain.
The degree of degradation varies with materials and their disruptive behavior.
