摘要: Abstract A microscopic imaging method using the fluorescent binding agent, fluorescamine, has been applied to determine presence and location of primary amines in selective layer TFC polyamide RO membranes. The such is attributed incomplete condensation reactions preparation membrane's active for fully aromatic concentration free greatest section most distant from external membrane surface. are effectively removed by combining rinsing with application oxidation agents. As delivered spiral wound modules they have already a large extent. In flat sheet still contain various extents amine depending on type supplier.
