Determination of Trace Amounts of Arsenic in Gas Field Sewage by Hydride Generation-Atomic Fluorescence Spectrometry

Jiang Li (Environment Monitoring Station,Chongqing Gas Mine,Southwest Oil & Gas Field,Chongqing 400021)  
Hydride generation atomic fluorescence spectrometry was adopted to determinate trace amounts of arsenic in gas field sewage.This method has the merits of less sample volumes,operaton convenience,higher sensitivity,higher accuracy and better repeatability.The linear range of determination was from 1 ng/mL to 200 ng/mL,the detected limit of this method was 0.0453 ng/mL while relative standard deviation less than 1.6% and mark on recovery ranging from 96.0% to 97.7%.This method obtained a satisfactory result for determining code sample and trace amounts of arsenic in gas field sewage.
