震后某工号建渣及土壤样品中铀的分析测定
|
摘要
采用激光荧光法对"5.12"地震后某工号建筑垃圾和土壤样品进行了铀的测定。方法检出下限D.L≤3×10-11g/mL,相对标准偏差RSD为7.4%,回收率达到86%~109%。对实验数据进行了分析和初步评价,结果表明,该工号所测样品铀含量基本处于天然本底水平。
Uranium in building trash and soil samples from "May 12" earthquake area were determined using laser fluorescence spectrophotometry.The detection limit,relative standard deviation(RSD) and recovery rate were ≤3×10-11g/mL,7.4% and 86%~109% respectively.The experimental data were analyzed and evaluated initially.The results showed that the uranium content of this location was at the normal level of background.
