초록
A new colorimetric method established for the determination of ampicillin was based on the reductions of phosphomolybdic acid by ampicillin to be resutled in a molybdenum blue which showed a mezimal absorbance at 770nm. The pH effects on a molybodenum blue solution was dependent significantly on temeprature, but the wave-length shift was not effected by the molybdenum blue.
