Abstract
Procedeul de recuperare a argintului si a suportului din deseurile de materiale fotosensibile, conform inventiei, prevede tratarea preliminara cu o solutie acida oxidanta cloruranta în cazul cînd deseurile contin argint metalic alaturi de hlogenura de argint, în vederea halogenarii acestuia, urmata de solubilizarea halogenurii de argint prin tratare cu un amestec de tiosulfat de sodiu si pirosulfit de potasiu sau prin solubilizarea directa a halogenurii de argint în amestecul mentionat cînd deseul nu contine argint metalic, urmata de separarea electrolitica a argintului din solutia obtinuta, suportul ramas fiind tratat în continuare cu solutie de hipoclorit de sodiu alcalinizata cu Na2CO3 sau NaOH pentru îndepartarea gelatinei în vederea utilizarii în alte scopuri.
