Titanium dioxide is the most abundantly used white pigment of the 20th century. The pigment is still in use, both in the production of contemporary art and for the conservation of older artwork as a retouching pigment. Unfortunately, next to its positive characteristics, the pigment has one major potential drawback: its photocatalytic activity that can cause degradation of artworks in which it is used. In this paper, we report on a new method to test the photocatalytic activity of different quality grades of titanium dioxide white pigments. This can be done quantitatively in a chemical lab or qualitatively in a quick and easy way, in a museum or artists' studio, with limited use of lab equipment. The photocatalytic degradation of an organic dye, acid blue 9, in an aqueous solution containing titanium dioxide, is followed over time by means of UV-Vis spectrophotometry. Dye solutions containing pigments with high photocatalytic activity lose their color within several hours of UVA exposure. On the other hand, dye solutions containing UV-stable titanium dioxide do not degrade within 24 h of UVA exposure. Insight in the photocatalytic activity of titanium white pigments, which can be obtained with this novel test, is of great importance for preventive conservation of modern art.

“…As a matter of fact, the discharge of such effluents in the environment is worrying for both toxicological and esthetical reasons. In this respect, the degradation of dyes either by chemical or biological processes is widely reported in the literature [2][3][4]. The main drawback of such techniques is that the complete degradation is seldom achieved [5].…”

“…It is also stated that these dyes resist degradation in activated sludge systems (Jank et al 1998). Under anaerobic conditions, the transformation of triphenylmethane dyes is presumably limited to reversible reactions like the reduction of malachite green (basic green 4) to leucomalachite green (Henderson et al 1997).…”
