摘　　要：目的：探讨使用石墨炉原子吸收光谱法直接测定尿中铅的检测方法。方法：选取1211份梧州市两家工厂的操作工人的晨尿样品，采用塞曼扣背景的石墨炉原子吸收光谱仪器，使用胶体钯醇水溶液作为基体改进剂进行测定。结果：在全部1211份尿样品之中有32份超过0．58μmo1／L的国标尿中铅轻度中毒指标。结论：本法背景干扰少，精密度和准确度高，尿样不需经过前处理和稀释就可以直接测定。Objective Using graphite furnace atomic absorption spectrometry determination of lead in urine directly. Methods Selected 1211 worker/morning urine, by graphite furnace atomic absorption spectrometer, colloid palladium alcohol aqueous solution was used as matrix modifier, to do determinetion. Results In all 1121 urine samples, there were 32 cace more than 0.58, u mol/L GB ofindex Conclusions This method with less background interference, high precision and accuracy, urine does not need pretreatment and dilution, can be directly determined.
