连续氢化物发生-ICP/AES测量乙烯原料中痕量砷

Determination of Trace Arsenic in Raw material Oil of Ethylene Industry by CF - HG - ICP/AES

连续氢化物发生-电感耦合等离子体发射光谱法(CF-HC-ICP/AES)测定乙烯工业原料油中痕量As。样品经萃取后加热消解,在选定条件下,测得As的检出限为0.21ng/ml。对标准物质和样品进行分析,结果令人满意。

The trace Arsenic in light raw material oil which was oxidized and extracted is detected by Continuous Flow - Hydride (Generation - Atomic Emission Spectromrtry. 'Ihe results showed that the detection limit of arsenic is 0.21ng/mL. And the satisfactory re-sults was obtained in analysis of standard and samples.
