Abstract
PURPOSE: The reverse osmosis membrane of an improved metal ion removal rate and water transmission rate by causing radical polymerization of nitrogen-contained monomer and alkyl metals in the plasma region of glow discharge thereby forming a high polymer film on porous plates.
CONSTITUTION: Porous substrates 2 are disposed on the glass support table 8 or the like in a hermetic vessel 1 and the inside of the vessel 1 is put in a vacuum state. Nitrogen-contained monomer such as of allyl amine, alkyl metals such as of diethyl zinc and inert gas such as argon are mixed under suitable partial pressures and the mixed gas is grawn through a raw material suction port 5 and is applied with suitable AC current. This causes glow discharge to be generated and the nitrogen- contained monomer and alkyl metals to be radical-polymerized by high energy in the region of a plasma state, whereby the reverse osmosis membrane being high polymer film is formed on the substrates 2. This membrane is an asymetrical thin film which is extremely thin and is utilized for desalination of sea water, expulsion of heavy metal ions, etc.
