Abstract

naznačen time, što se kiseli rastvori, koji se sastoje od 60 do 95 zapreminskih % vode, 5 do 40 zapr.% azotne kiseline i 2,5 do 10 zapr.% sumporne kiseline, a koji su korišćeni za proizvodnju tamnosivih do crnih pokrivnih slojeva na oblikovanim proizvodima do legura cinka, bakra i titana, a prvenstveno na valjanim limovima i trakama, propuštaju kroz dijalizatorsku ćeliju ograničenu permselektivnom membranom, koja se nalazi izmedju jednog para elektroda.
