A sensitive spectrophotometric method for the assay of micro amount of amoxicillin trihydrate (AmoxT) in aqueous solution has been worked out. The method is based on the coupling of AmoxT with diazotized m– nitroaniline (DmNA) in basic medium. The azo dye formed is water – soluble, stable, and shows maximum absorption at 436 nm, Beer’s law is obeyed over the range (3-30) g.ml with a molar absorptivity of 2.600610 l.mol -1 .cm -1 and Sandell ҆s sensitivity index of 0.0161 μg.cm -2 , a relative… Expand
