This scientific research includes sixteen of the most common bentonites on Bulgarian market, which are used by Bulgarian wine cellars in order to achieve colloidal stability of wines. There are bentonites with different composition: sodium, calcium, sodium-calcium, activated calcium, as well as mixtures between natural calcium and activated calcium. Their capacity to transfer elements from and to a model solution with wine parameters have been investigated. Inductively coupled plasma-optical emission spectrometry (ICP-OES), inductively coupled plasma with mass spectrometry (ICP-MS), flame atomic emission spectrometry (FAES) and flame atomic absorption spectrometry (FAAS) techniques have been used. The selected elements, which are subject to this study, are important for human health as well as for the stability of wine clarity.
