摘要: Volatile organochlorine compounds (VOCCs) formed during kraft pulp bleaching were determined from the effluent at bleach plants and waste water treatment of three mills means by a purge trap injector connected to GCMS. Among seventeen VOCCs identified when ClO2 was used in bleaching, chloroform constituted major fraction dichloroacetic acid methyl ester 2,5-dichlorothiophene also abundant. The formation related use with lower charge yielding less hardly any being non-chlorinated agents used.
