Abstract

Application of H-point standard addition method for spectrophotometric determination of 2-tert-butyl 4-methylphenol in the presence of bis(4-metyl hydroxy phenyl)methane

Author(s): Reza Hajian, Nafiseh Shams, Mahboobeh Matin

H-point standard addition method (HPSAM) has been applied for determination of 2-tert-butyl 4-methylphenol which acts as an intermediate in the presence of Bis (4-metyl hydroxy phenyl) Methane (product) in trace levels. Absorbance of the mixed spectra at the two pairs of wavelengths, 274.8 and 290.6 nm were monitored with the addition of standard solutions of 2- tert-butyl 4-methylphenol. The method is able to accurately determine intermediate in the intermediate/product ratio of 1:10 (w/w). Accuracy and reproducibility of the determination method on the various known amounts were evaluated in their binary mixtures. To investigate selectivity of the method and to ensure that no serious interferences were observed the effects of different species on the determination of 2-tert-butyl 4-methyl phenol were also studied. The recommended procedure was successfully applied to some synthetic mixtures.
