| Abstract: | A reversed-phase high performance liquid chromatography method was diescribed for the deter-mination of pollutants in wastewater from synthesis of 3,3'-dichlorobenzidine hydrochloride.Station-ary phases of Zorbax-ODS and mobile phase of acetonitrile-water (70: 30, V/V) were applied forthis purpose.The analysis revealed that the wastewater contained several pollutants, including3,3'-dichlorobenzidine hydrochloride,o-chloroaniline and other two unknown ones. |
