摘要
用脉冲辐解法研究了稀土硝酸盐对生成超氧阴离子自由基 (·O2 - )的抑制作用。稀土硝酸盐对脉冲辐解充氧甲酸钠溶液产生·O2 - 有明显的抑制作用 ,抑制率在 2 8%～ 92 %之间 ,且稀土硝酸盐浓度与其对·O2 - 的抑制作用之间存在明显的剂量效应关系。
The inhibition effect of rare earth on the production of ·O 2 - produced by irradiation of aqueous sodium formate saturated with O 2 with high energy pulse electron beam was studied. The result indicates that rare earth nitrates obviously inhibit the production of ·O 2 -. The inhibition rate is between 28 6%～92%. The inhibition effect increases with the increase of rare earth nitrates concentration. The distinguish dose effect relationship was observed in the experiment.
