Abstract

We report here the results about the sulphur concentration in ancient stones and its removal after the application of UV laser action. A portable apparatus for energy-dispersive X-ray fluorescence (EDXRF) was utilised to measure the sulphur concentration before and after laser cleansing. After laser application the sulphur concentration decrased to 1.2% w/w whilst the initial value was 2.8% w/w. The laser energy density was about 1 J/cm² and the efficient shot number was approximately 30 with a rate of 1Hz.
