Cyanides and rhodanides are toxic compounds with a negative influence on the environment and the human health. Cyanides are known as a important raw material in pharmaceutical, cosmetics, medical and agricultural product manufacture and in processing processes of the metallurgical industry. Reactions between cyanides and sulphur result with the formation of rhodanides or thiocyanites which are charaterized as compunds with lower toxicity but higher stability than cyanides. With the development of the industry and the increase in production capacity, the amount of cyanide and rhodanides that ends up in the environment within wastewaters increases. Because of that, it is necessary to carry out the wastewater treatment before the discharging to decrease their presence in the environment. Advanced oxidation processes are a type of processes which are used for treating that kind of polluted water. They are based on the usage of oxidizing agents which successfully result with the decomposition of unwanted organic compounds. This work deals with the removal od cyanides (CN-) and rhodanides (SCN-) from model solutions by the advanced oxidation processes using photolysis, UV/H2O2 and UV/S2O82- at pH values 4, 7 and 10. The ratio of pollutants (CN- and SCN-) to oxidizing agents (H2O2 and S2O82-) was 1:10, while the wavelength of the UV radiation was 254 nm The results showed that the usage of the UV/S2O82- method under lower pH values was the most effient for both pollutants. The UV/S2O82- method is the most efficient with 99.26% of CN- and 80.26% of SCN- removed at pH=4. Minimal efficiencies in the removal of both pollutants were recorded with pure photolysis, where only 40.90% of CN- (pH=7) and 21.49% of SCN- (pH=10) were removed. The fastest kinetics of the CN- degradation is by the UV/S2O82- method (k = 0.0806 s^-1) at pH=4, while the slowest is during pure photolysis (k = 0.0076 s^-1) at pH=7. The fastest degradation of SCN- is by the UV/S2O82- method (k = 0.027 s^-1) at pH=4, while the slowest is during pure photolysis (k = 0.0041 s^-1) at pH=10. The stated removal processes of CN- and SCN- contain first order reactions, that are actually considered to be pseudo-first order due to the large number of radical reactions.
