Continuous flow injection analysis via NAG-۴SX۳-۳D analyzer utilized to determination of resorcinol

A fast and sensitive method for detecting resorcinol by producing yellowish-green color species using the reaction of potassium dichromate with resorcinol in a sulfuric acid medium. NAG-۴SX۳-۳D analyzer was used to evaluate the transducer energy response. To improve the sensitivity of the newly developed approach, the relevant parameter was explored. The linear range (۰.۰۵-۳۲) mmol.L-۱ for resorcinol measurement and RSD percent for the repetition (n=۶) was significantly lower than ۰.۳% for (۰.۷, ۲۳ millimol.L-۱) with L.O.D.=۴۸.۱۶۸۷ ng/sample from the progressive dilution across the calibration graph's lowest concentration linear dynamic range (r=۰.۹۹۹۷), (correlation coefficient), percentage linearity (R۲ %=۹۹.۹۵). The proposed approach was compared to the previous technique (UV-spectrophotometric at λmax=۲۷۳ nm). It can be concluded that, in addition to the technique's sensitivity (developed) and the use of a few chemicals, it outperforms the ۱۰ mm irradiation of the classic reference method. Furthermore, continual dilution in CFIA enables the handling of high or low concentrations, opening up a larger range of applications. Based on the foregoing, the developed methodology is judged to be the most suited for resorcinol molecules compared to the reference techniques.
