Spectrophotometric determination of 4 nitroaniline using n 1 naphthyl ethylenediamine dihydrochloride in parts per million level


, : Spectrophotometric determination of 4 nitroaniline using n 1 naphthyl ethylenediamine dihydrochloride in parts per million level. Indian Journal of Environmental Health 27(2): 105-109

The method describes the determination of 4-nitroaniline (PNA) in which PNA is diazotised with sodium nitrite in the presence of hydrochloric acid and subsequently coupled with N(1-naphthyl) ethylene diamine dihydrochloride (NEDA) in acid medium. The absorbance of the purple colored dye so formed is measured at 545 nm. The molar absorptivity and Sandell's sensitivity are 6.6 .times. 104 l .cntdot. mol-1 cm11 and 0.0021 .mu.g cm-2 respectively. Several common interferents like phenols, nitro compounds, aldehydes, benzene, ketones, etc. present in polluted water do not interfere. On the other hand, primary aromatic amines when present in high concentrations interfere.

Rapid acute neuronal tolerance (RANT) to the depressant effects of ethanol (EtOH) is a desensitization of EtOH-induced depression of neuronal firing that develops over the first 5 to 7 min of EtOH exposure. This phenomenon has been hypothesized to...
