| Abstract: | The sorption of 1-naphthylamine (NA) as 4-nitrobenzeneazonaphthylamine was studied as function of phase contact time, aqueous acidity, 4-nitrophenyldiazonium tetrafluoroborate (NPD) concentration, and NA concentration. A highly efficient method for the sorption/photometric determination of NA was developed. |
