Abstract
A method of direct aqueous injection analysis of volatile trace sulfur compounds in waste or contaminated water is reported. The detection l imits of H2S, COS, and several mercaptans range from several ng/mL to several tens of ng/mL. The method precision is approximately 10%. Cont amination problems, standard curve preparation, injection volume and s everal problems related to the method development and sample analysis are also addressed in this paper.
