J. Fekete et F. Ritz, A NEW APPROACH FOR THE DETERMINATION OF ORGANOBROMINE IN HARMFUL WASTE, JOURNAL OF THERMAL ANALYSIS AND CALORIMETRY, 52(1), 1998, pp. 249-256
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.
