| Abstract |
A method for the determination of benzidine and 3,3'-dichlorobenzidine in wastewater was developed. This method, based on the use of high performance liquid chromatography with electrochemical detection, is selective for readily oxidized, basic compounds, and can detect as little as 0.1 ppb of benzidine and DCB in many types of aqueous samples, including surface water, municipal sewage, and industrial effluent samples. However, several dye plant effluents contained many oxidizable materials which decreased the sensitivity of the method to 1 ppb for benzidine and DCB. Apparent levels of 10-20 ppb of benzidine were present in the dye plant effluents. |
