A spectrophotometric method for the determination of penicillin.

Simultaneous spectrophotometric determination of ampicillin and penicillin in human plasma using multivariate calibration

An analytical methodology based on spectrophotometric and partial least squares (PLS) algorithm for thesimultaneous determination of ampicillin and penicillin in human plasma was developed and validated. Themultivariate model was developed as a binary calibration model and it was built and validated with anindependent set of synthesis and real samples in presence of matrix. It is shown how a de...

SPECTROPHOTOMETRIC REACTION RATE METHOD FOR THE DETERMINATION OF SLWR BASED ON ITS CATALYTIC EFFEICT ON THE OXIDATION OF GLLOCYANW BY PER0XYDISULPTE

A sensitive and selective procedure was developed for the spectrophotometric determination of silver by its catalytic effect on the oxidation of gallocyanine by peroxydisulphate in acidic media at 540 nm. Silver can be determined in the range of 0.001-0.500 µg/ml with a limit of detection of 0.0005 µg/ml, by a fixed-time method of 4.0 min from initiation of the reaction, The relative standa...

Kinetic Spectrophotometric Method for Determination of S032- Using Methylen blue

The present work reports a kinetic spectrophotometric method for the determination of traceamounts of sulphite that is based on inhibitory effect of sulphite on the oxidation of Methyleneblue (MB) in acidic media. The reaction is followed spectrophotometrically by monitoring thedecrease in absorbance of MB at 664 nm with a fixed time of 0.5-4.5 minutes. It was found thatsulphite exert a strong ...
