This study investigates the effect FeCl3 on the radiation stability of the ionic liquid,1-butyl-3-methylimidazolium chloride(BmimCl) over a wide dose range of 0 to 1000 kGy under γ-ray radiation.The ionic liquid species,BmimFeCl4,was formed by adding FeCl3 into BmimCl.The results showed that the presence of FeCl4-significantly improved the radiation resistance of BmimCl,wherein the effect was more pronounced at higher FeCl4-content.Meanwhile,under irradiation,Fe(II) was generated from Fe(III),which was reduced by solvated electron.In addition,the concentration of Fe(II) increased with low level of absorbed dose,but leveled off at higher doses.Moreover,the radiation yield of the solvated electrons of BmimCl was further estimated at approximately 0.358±0.01 μmol/J in BmimCl-7 mol% FeCl3 system.
This study investigates the effect FeC13 on the radiation stability of the ionic liquid, 1-butyl-3-methylimidazolium chloride (BmimCl) over a wide dose range of 0 to 1000 kGy under y-ray radiation. The ionic liquid species, BmimFeC14, was formed by adding FeC13 into BmimCl. The results showed that the presence of FeC14- significantly improved the radiation resistance of BmimCl, wherein the effect was more pronounced at higher FeC14- content. Meanwhile, under irradiation, Fe(II) was generated from Fe(III), which was reduced by solvated electron. In addition, the concentration of Fe(II) increased with low level of absorbed dose, but leveled off at higher doses. Moreover, the radiation yield of the solvated electrons of BmimC1 was further estimated at approximately 0.358_+0.01 μmol/J in BmimCl-7 mo1% FeCl3 system.
