Simultaneous spectrophotometric determination of oA and pA was made with HPSAM at 480 and 610 nm when
Based on the optimum conditions obtained above and cited in (Table 4), HPSAM has been applied for simultaneous determination of oA and pA isomers in binary mixtures.
To select the appropriate wavelength pair for using HPSAM the following principles should be applied.
Amounts found of oA and pA by applying HPSAM at different pairs of wavelengths.
Results of several experiments for the analysis of oA- pA mixtures considering oA as analyte at different concentration ratios by HPSAM.
Results of several experiments for the analysis of pA-oA mixtures considering pA as analyte at different concentration ratios by HPSAM.
The influence of the presence of several cations and anions on the determination of 2.0 ug ml-1 of oA and pA have been investigated by HPSAM at wavelengths 480 and 610 nm.
