摘要:

Because arsenic poison catalysts during process operations and also is an environmental contaminant, the determination of total arsenic in natural gasoline, gas condensate and its products is of primary concern. Many methods available for the determination of arsenic require sample pretreatment and subsequent analysis on an aqueous matrix. Unfortunately, those methods could not get a satisfactory result because natural gasoline, gas condensate and its products may contain a variety of organic arsenic compounds which have lower boiling point than inorganic arsenic.
