The assessment of the penetration depth of conservation treatments applied to cultural heritage stone materials is a burning issue in conservation science. Several analytical approaches have been proposed but, at present, many of them are not fully e

Dissolution kinetics of borogypsum in di-ammonium hydrogen phosphate solutions

Autor: Havva Mumcu Şimşek, Rövşen Guliyev, Ayşe Vildan Beşe

Publikováno v: International Journal of Hydrogen Energy. 43:20262-20270

This work examines the dissolution kinetics of borogypsum in di-ammonium hydrogen phosphate solutions ((NH 4 ) 2 PO 4 ) in a batch reactor. The parameters selected were the reaction temperature (15–53 °C), di-ammonium hydrogen phosphate concentrat
