Treatment of Textile Wastewater in the Fenton Process in the Presence of Iron and Nickel Nanocompounds
Journal Title: Fibres and Textiles in Eastern Europe - Year 2016, Vol 24, Issue 5
Abstract
The aim of the studies was to determine the efficiency of wastewater treatment by the Fenton method in the presence of iron and nickel nanocompounds and to compare it with the classical Fenton method. The subject of the studies was textile wastewater generated during the dyeing of cellulose fibres. Wastewater colour and COD were determined in the samples before and after treatment using proper analytical methods. The Fenton process changed by the addition of iron and nickel nanocompounds was optimized taking into consideration the effect of the following parameters: doses of iron and nickel nanocompounds, the hydrogen peroxide dose and the pH of the solution on treatment efficiency. The decomposition of dyes was complete, with the reduction of COD reaching 57%. Optimum doses of iron and nickel oxide nanopowders were 0.02 g/dm3. It was found that the efficiency of pollutant decomposition in the processes of treatment in which iron and nickel oxide nanopowders were applied, was higher than in the classical method.
