Research On The Properties And Applications Of Metal Ultrafiltration Membrane

As an important chemical industrial product, membrane is used for concentration, purification and separation mainly. There are many kinds of membrane filtrations, and ultrafiltration is the most popular one. The objective of this thesis is nickel-base tubular ultrafiltration membrane, which was used for the gaseous diffusion process only in nuclear industry years ago.The research on the membrane is based on theoretical derivation and experiment. The purpose is to search other possible applications except for UF6 gas separation of the membrane.Pore is one of the most important parameters of membrane, and the material is another."Pore"means the average pore size, the pore size distribution, the effective porosity and the specific surface area, pore volume, and so on."Material"means the material and its purity of the membrane. This thesis carried out experiments for all of them and got good results. That meant the membrane could be used for many purposes, such as air filtration, pure water production, waste water treatment, juice filtration, and so on. Some of them are profitable.Based on the research results of properties above, the research on applications of the membrane were carried out. First of all, a set of device was designed and constructed. And then, a lot of gas and liquid specimens were filtered with the membrane and the device. Experiment results supported the conclusion above strongly. Further more, the membrane might be processed to use for hydrogen gas and nano-materials production.
