Abstract—In this paper, a novel large size (50x50mm2) anodic gas filtration); 3) Ultra-filtration (solute size: 5nm~100nm,
porous alumina membrane specially used in hemodialysis process such as hemodialysis); 4) Reverse osmosis or nano-filtration
is developed. By using a two-step anodization fabrication method, (only water can sometimes pass through the porous membrane).
a semi-permeable membrane with nano-sized pores is produced.
Comparing with spongy style pores located on polymer In the process of hemodialysis, due to position of
membranes, this membrane has straight channel pores. And the blood and variety nutrition needed by a healthy human
these pores are uniform in size. Experimental results in this body, the ideal membrane should be highly permeable to water,
paper also show that the relationship between membrane anic or anic metabolites, and capable for retaining
size and anodization voltage follows linear rule on the scale of plasma proteins. The membrane should also be patible
several nano-meters. These intrins
