title: Study of toxic elements in bentonite suspensions and their migration during wine processing
abstract: Abstract. Bentonites are widely used for processing must, juices, wines, distilleries in order to lighten and stabilize them against turbidity. Bentonites contain metal cations in the form of oxides and exchange ions, including toxic elements that can migrate into it in contact with wine materials. The aim of the work is to investigate the content of iron, copper and toxic elements in suspensions of minerals from various deposits and their migration into processed wine materials.
