Abstract:Deacidification of aged paper was studied using natural acid stripping agents. Acid papers were deacidified by soaking in the natural acid stripping agents TS3 and TS4. Effects of temperature, time and dilution ratio of the acid stripping agents on deacidification and chromaticity of the paper were investigated. Results showed that suitable raising temperature and extending time of deacidification was beneficial to enhance deacidification, but deacidification effect decreased when the acid stripping agents were diluted. After deacidification, paper chromaticity changed slightly and paper color became taupe.
