HPLC methods can be ntilized for the pre-concentration of aromatic amines from polluted waters on silica gel or octadecyl silica (ODS) colnmns [55], The determination is then performed by RP HPLC using ODS packings as the stationary phases and a mixture of methanol, isopropanol, and water as the mobile phase [55], RP HPLC with diode array detector (DAD) methods coupled on-line with a continnons seqnential anaerobic/aerobic reactor system have been employed in wastewaters treatments [56], A continnons monitoring of the possible presence of aromatic amines in azo dyes wastes is based on indncing in the waste, the reaction of a reduction of the dye, followed by HPLC/ UV or HPLC/MS analysis [57-59], The redncing agent solutions are sodium dithionite or tin(II) chloride in an aqneons acidic medinm at 70°C, followed by SPE [58,59], LLE [60,61], or SEE [60-62],... 

A bioreactor is a vessel in which biochemical transformation of reactants occurs by the action of biological agents such as organisms or in vitro cellular components such as enzymes. This type of reactor is widely used in food and fermentation industries, in waste treatment, and in many biomedical facilities. There are two broad categories of bioreactors fermentation and enzyme (cell-free) reactors. Depending on the process requirements (aerobic, anaerobic, solid state, immobilized), numerous subdivisions of this classification are possible (Moo-Young, 1986).

This combination of anaerobic and aerobic environment adds some complexity to the process but enables larger loads to be purified such as shown in Figure 2-23. One of the primary effluent gasses is trimethylamine. This tertiary amine has the very characteristic odor of rotten fish. Combustion methods can be used to treat this waste but these will produce NOj, effluents unless very special measures are employed in waste treatment. An alternative wet chemical processes was developed (Bohrer, 1999). The liquid solution waste can also be oxidized to produce a non-odoriferous solid using hydrogen peroxide. This alternative waste treatment process keeps the nitrogen fixed, reducing the atmospheric... 

Talking about biodegradation of plastics in a liquid environment usually means the natural degradation in sweet water (lakes, rivers), in a marine environment or in aerobic and anaerobic sludges (waste water treatment). However, many degradation studies with plastics in laboratories were performed in defined synthetic or in complex liquid nutrient broths and this also can be regarded as a degradation in a liquid environment. While from...
