应用流动注射在线萃取技术将 Pd Cl62 -萃入 2 -巯基苯并噻唑 -甲基异丁基酮直接进行石墨炉原子吸收测定。研究了流动注射在线萃取 -石墨炉原子吸收光谱法测定地质样品中钯的实验条件、流路参数等。采样速率为 2 0样 /h,RSD( n=1 0 )为 4 .8% ,测定 Pd的特征质量为 2 .6× 1 0 -11g。
The determination of Pd Cl62 - in 2 - mercaptobenzothiazole - methyl isobutyl ketone by graphite furnace atomic absorption spectrometry was carried out by flow injection on - line extraction. The flow injection on-line extraction - graphite furnace atomic absorption spectrometry determination of geological samples of palladium experimental conditions, flow parameters and so on. The sampling rate was 20 h / h, RSD (n = 10) was 4.8%, and the characteristic mass of Pd was determined to be 2.6 × 10 -11 g.
