Abstract
Abstract A large portion of solvent selection and solubility calculations by Conservators of Works of Art are still done with solubility parameters or its Teas variation scheme. In spite its empirical character entailing the risk of notable failures, this is a simple and often successful scheme. The central objective of the present work is to provide with an alternative simple method for the above and related calculations but with sound thermodynamic basis for more reliable estimations. The method is known in the literature as the Partial Solvation Parameter (PSP) approach. With the Conservator in mind, the method is simplified and the working equations are reported in their simplest analytical form. Examples of calculations are reported which will facilitate understanding and efficient use of the method. The calculations cover bulk phases as well as interfaces and may be used for the rational design of conservation and numerous other processes.
