Flotace papíru

Abstract

This thesis is focused on possibilities of removing printing ink from recycling paper trough the use of flotation technology. In the first part I am describing present status of recycling in the Czech Republic and in the Europien Union. After that follows description of flotation technology – on which principle it works; agents which have influence on it. After that follows chapter, which is focused on recycling paper. In this chapter I am describing the individual steps of recycling paper and also the separated components of flotation – paper and printing ink. The experimental part is describing laboratory research – the preparation of entry for flotation, fulfilment of flotation tests, the preparation of samples for analysis and also the product of analysis, which I am evaluating in the next chapter.
