| Abstract: | 1-butyl-3-methylimidazolim hexafluorophosphate(BMIM]PF_6)is one of the most commonly used ionic liquid.In this paper,all the possible factors,which have effect on removal efficiency of 1-Butyl-3-methylimid-azolim hexafluorophosphate through Fe/C micro electrolysis,are studied symmetrically.The orthogonal experiment and single factor test show that the factors arranged in important order are as the follows:the ratio of C/Fe,pH,reaction time.The results also show such optimum values of parameters as 3 g·l~(-1) of iron scarp dosage,2.5 of water pH,2 of C/Fe ratio,60-90min of reaction time.And the removal efficiency is over 90% at this optimum reaction conditions.The decomposing reaction is a third order. |
