Abstract：

The　oxidative　degradation　of　chlorinated　ethylenes　with　a　metal-oxo　reagent,　potassium　ferrate　(K2FeO4),　is　investigated　in　this　paper.　The　encapsulated　K2FeO4　was　prepared　by　a　molten　suspension　and　cooling　method,　with　paraffin　wax　and　K2FeO4　solid　as　the　encapsulating　wall　and　encapsulated　core,　respectively.　The　effects　of　three　main　factors,　stirring　time,　ultrasonic　time　and　temperature　of　the　water　bath,　on　the　preparation　of　encapsulated　ferrate　were　studied.　The　IR　and　XRD　spectra　showed　that　ferrate　was　stable　after　encapsulation.　Experiments　also　showed　that　the　release　process　of　K2FeO4　from　the　encapsulated　particles　includes　two　phases:　(1)　the　uncoated　ferrate　was　immediately　dissolved　(
