发明名称 Hyperpure hydrogen peroxide production using reverse osmosis unit, used for processing semiconductors
摘要 <p>Hydrogen peroxide of 60 - 70 % concentration, and not containing stabilizers, from an industrial plant is purified by reverse osmosis within a unit which is part of the plant. Hyperpure hydrogen is obtained by a process whereby the product is fed to the purification unit wherein high purity permeate is separated and recycled to the production plant. The hydrogen peroxide is used without addition of a stabilizing agent.</p>
