摘要
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。
A new method for the determination of trace palladium in geological samples by graphite furnace atomic absorption spectrometry with solvent extraction flow injection was proposed. Experiment condition and manifold parameters were investigated in detail. The characteristic mass is 2.6×10 -11 g and the precision is 4.8%( n =10). The sample throughput for palladium is 20/h.
