The paper provides comprehensive information on the recent progress of the use of potassium ferrate(VI) (K2FeO4) for the removal of selected pollutants from water and wastewater. K2FeO4 provides great potential for diverse environmental applications without harm to the natural environment. Therefore K2FeO4 was used in removal of cyanides from gold ore purification processes, degradation of dyes and organic compounds in wastewater and algae removal in the water treatment process. The quoted research results indicate that K2FeO4 due to its strong oxidizing and coagulating properties, could be an alternative to the use of Advanced Oxidation Processes (AOPs) or be an additional option to conventional methods of water and wastewater treatment. As a result of using K2FeO4, the emerge intermediates of the impurities decomposition are nontoxic or show less toxicity than the initial substrates. The use of K2FeO4 is also associated with certain limitations of technical and technological nature, which requires further research in order to use its high efficiency in the degradation of various types of contamination on a technical scale.

Niniejsza praca opisuje oznaczanie cyjanków w surowych i oczyszczonych ściekach koksowniczych. Przeprowadzono optymalizację oznaczania i kalibrację układu pomiarowego w zakresie: określania liniowowści, granic wykrywalności, granic oznaczalności i precyzji oznaczeń.

Cyanides are strongly and fast-acting poison, however, depending on the cyanide source there are several types of cyanide of varying toxicity. The determination of cyanides usually involves two steps. In the first step, the sample is distillate to convert all cyanide into HCN, which is absorbed in a high pH solution (e.g. NaOH). In the second step, cyanides are usually determined by one's of the following methods: titration, spectrophotometric or potentiometric. The paper describes determination of cyanides in raw and purified waste water from coking plants. Method optimalisation and calibration of analytical system used, in the range of: linearity, limit of determination, limit of quantification, and method accuracy was carried out.
