The major instructive spectral property of BPA in a UV-visible spectrum is between the wavelength of 240 -300 nm. The UV-visible spectrophotometer was used to analyze the stock solution and the wavelength of maximum absorbance was determined to be 277.2 nm. The instrument was set at this wavelength in order to generate a calibration curve. The absorbance of each working standard having different concentrations was then monitored at maximum wavelength of absorbance (277.2 nm). Using the absorbance data for working standards, calibration curve was prepared by plotting absorbance of working standards against their respective concentrations. Using the equation of straight line of the form y = mx ± c, concentration equations were generated using a simple linear regression analysis in accordance with Beer Lambert law: A = ECl. An excellent correlation coefficient was obtained.
