Mutagenic influence was also exerted by nitrophenols and nitrated aminophenols. In the test with the use of Salmonella typhimuriummutagenic activity was observed for 2,3-dinitrophenol, 2,5-dinitrophenol, 3,4-dinitrophe-nol, 2,4,6-trinitrophenol and 2-nitro-5-aminophenol.
Aminophenol toxicity is related with generation of semiquinones and superoxide radicals that damage a cell's biomolecules.
The protection of metal surface against corrosion by aromatic diamine and aminophenol based polymers was reported on iron [12], copper [13], mild steel [14], and stainless steel [15].
In this present work, isomers of aminophenol were synthesized by chemical oxidation method and characterized by different spectroscopic techniques.
In three polymers the peaks around 1147 [cm.sup.-1] are ascribed to the stretching of the C-O-C linkages [24] and further support that the aminophenol changed into poly aminophenol.
However, no studies of the electrooxidation of these DNA nitrogenated bases on graphite electrode, modified with polymeric films derived from aminophenols, were found in the open literature.
The aim of this work was to investigate the electropolymerization of aminophenols onto graphite electrodes in more acidic media, as well as the electrochemical and morphological characterization of the modified electrodes produced and the immobilization of nitrogenated bases on these electrodes.
most phenols including phenol, chlorophenols, nitrophenols and aminophenols are characterized by toxic activity.
Voltammetric method has been reported for determination of aminophenols in a mixtures based on the oxidation peak potential difference between mA and oA and oA and pA using single- wall carbon nanotubes modified glassy carbon electrode [3].
The results showed that 2000 ug ml-1 Na+, K + , Mg2+ , SO4 2[?], NO 3 [?], Cl[?], and 1000, 250 and 100 ug ml -1 Al 3+ , Fe 2+ and Ca 2+ respectively did not interfere with the determination of aminophenols. Some aliphatic amines as interferents have been investigated to examine the selectivity of the method.

One, referred to as the "primary," is exemplified by the phenylenediamines, and the other, often an aminophenol, is known as the "coupler." These compounds are stable and do not react with each other until they are mixed with hydrogen peroxide.
