A NEW APPROACH FOR THE DETERMINATION OF ORGANOBROMINE IN HARMFUL WASTE

Determination and estimation of organic sulphur, nitrogen, phosphor an d halides in harmful chemical waste and estimation of emission of SO2, NOX, HCI, HBr or HI during incineration are the primary task of risk assessment. In our paper we present a new analytical approach for dete rmination of bromine in a heterogeneous sample. The method applied is based on combustion of chemical waste under oxygen atmosphere (pressur e 20 bars) and transformation to corresponding anions. These anions ca n be measured by ion chromatography. Using this method all hetero atom s can be transformed to corresponding anions (except for oxygen) and c an be measured by ion chromatography. In this paper we report of deter mination of bromine content of chemical waste. During the combustion o f organobromine compounds different types of inorganic bromine are for med. All types of bromine must be converted to Br-. To fulfil it the a bove, ascorbic acid solution was used for absorbing and transforming a ll types bromine compounds to Br-. We will discuss all the details abo ut this new approach and give all the parameters to get efficient conv ersion from organic bromine to bromide anions.
