Encapsulation of micro-sized barium ferrate(VI) and its effectiveness in removing clomazone pesticide from water

Synthesis of micro- and nano-sized crystalline BaFeO 4 particles by precipitation from the electrochemically synthesized potassium ferrate(VI) solution by means of barium hydroxide and its encapsulation in paraffin wax were explored using scanning electron microscopy, X-ray diffraction spectroscopy and FTIR spectroscopy. Experimental results showed effective synthesis of the micro-sized and nano-sized BaFeO 4 particles and their coating by the paraffin wax layer. The encapsulated micro- and nano-sized particles of BaFeO 4 were applied in investigating the possibility of degradation of pesticide clomazone in water. The removal of clomazone from water by oxidation using encapsulated BaFeO 4 could be almost 95%.
