摘　　要：由于可溶性钡盐对生物体有较大的毒性,因此对固体废物毒性浸出液中钡的含量测定具有重要意义。本文采用水平振荡及翻转振荡两种不同的方式对固体废物样品进行浸出处理,并采用ICP-MS对浸出液中钡的含量进行测定,结果显示,采用翻转振荡法对固体废物样品进行处理后浸出液中钡的测定平均值为3.15 mg/L,采用水平振荡法对固体废物样品进行处理后浸出液中钡的平均值为0.81 mg/L。由此表明,通过翻转振荡法处理固体废物样品时钡元素的浸出效率高于水平振荡法。同时,采用翻转振荡法处理固体废物样品得到的相对标准偏差低于水平振荡法。因此,在固体废物样品浸出处理时选择翻转振荡法能够得到更好的精密度及更高的含量测定值。Due to the significant toxicity of soluble barium salts to organisms,it is of great significance to determine the content of barium in the toxic leaching solution of solid waste.Two different methods,horizontal oscillation and Flipping oscillation,were used to leach solid waste samples,and ICP-MS was used to determine the content of barium in the leaching solution.The results showed that the average value of barium in the leachate of solid waste samples treated by flipping oscillation method was 3.15 mg/L,and the average value of barium in the leachate of solid waste samples treated by horizontal oscillation method was 0.81 mg/L,this indicated that the leaching efficiency of barium element in solid waste samples treated by flipping oscillation method was higher than that of horizontal oscillation method.Meanwhile,the relative standard deviation obtained by using the flipping oscillation method to treat solid waste samples was lower than that obtained by the horizontal oscillation method.Therefore,choosing the flipping oscillation method during the leaching treatment of solid waste samples can achieve better precision and higher content determination values.
