建立了火焰原子吸收光谱法快速测定染料中铅(Pb)的方法.将液体染料样品直接稀释配制、固体染料样品以超声溶解8min制备成测试液,采用标准加入法测定液体染料样品与固体染料样品中的铅含量.在选定的仪器测定条件下,该法测定结果与国标法(GB 20814—2006)混酸消解处理染料样品测定结果相比较相对误差≤5.09%,加标回收率为93.4%~104%,检出限为0.087μg/mL(n=15),5.00μg/mL Pb标准溶液平行测定15次,所得Pb吸光度的相对标准偏差为3.76%(n=15).该方法操作简便、快速、准确可靠,可代替国标法应用于染料样品中铅含量的测定. A method for the rapid determination of lead (Pb) in dye by flame atomic absorption spectrometry was established.The liquid dye sample was directly diluted and prepared, the solid dye sample was dissolved by ultrasonic for 8min to prepare the test solution, and the liquid dye sample and the solid dye sample In the selected instrument measurement conditions, the determination of the method with the national standard method (GB 20814-2006) mixed acid digestion dye sample measurement results compared to the relative error ≤ 5.09%, the recovery was 93.4% The relative standard deviation of the obtained Pb absorbance was 3.76% (n = 15). The method was simple and easy to operate, and the detection limit was 0.087μg / mL (n = 15) Fast, accurate and reliable, can replace the national standard method for the determination of lead in dye samples.
