Two types of chloramine have been used in the past as a bleach for paper. Chloramine-B, introduced in 1937, was eventually replaced by the more easily controllable chloramine-T which itself proved problematic: it reacts with aluminum and other metals precipitating residues that are hard to remove. Chloramine-T is now used as a disinfectant, antiseptic, and biocide. In conservation it is used for removing fungal stains from stone and in bleaching treatments of aged paper. ]]></LexicalValue></ScopeNote><NonPreferredTerm dc:identifier="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31343387" xml:lang="en">	<LexicalValue>chloramines</LexicalValue>		<dcterms:created></dcterms:created>		<USE>http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31343386</USE></NonPreferredTerm><HasHierRelConcept Role="BT">http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31319736</HasHierRelConcept></ThesaurusConcept></Thesaurus>
