title: Qualitative determination of 10,10'-oxybisphenoxarsine and decabromodiphenyl ether in plastics.
abstract: Plastics destined for facilities holding aquatic fauna, such as aquaculture and aquatic toxicology laboratories, were studied. The plastics were extracted with dichloromethane. The fungicide 10,10'-oxybisphenoxarsine (OBPA) was detected by silver nitrate after cleanup on a silica cartridge and TLC in petroleum ether-diethyl ether-acetic acid 80:20:1. The flame retardant decabromodiphenyl ether (DBDPO) was crystallized from dichloromethane and confirmed by IR spectrum. A UV-spectrophotometric method is suggested for the estimation of the leaching potential of additives from plastics.
