The results show that the potassium ferrate can degrade mg effectively , the degradation rate of mg enhance with the increase of the dosage of potassium ferrate .
Potassium ferrate was employed to degrade the malachite green ( mg ) in fishery water . The influences of some factors such as the reaction time , beginning ph value of reaction solution , initial mg concentration and the dosage of potassium ferrate on the degradation of mg were discussed .
