continuous flow injection analysis via nag-4sx3-3d 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-4sx3-3d 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 (0.05-32) mmol.l^-1 for resorcinol measurement and rsd percent for the repetition (n=6) was significantly lower than 0.3% for (0.7, 23 millimol.l^-1) with l.o.d.=48.1687 ng/sample from the progressive dilution across the calibration graph's lowest concentration linear dynamic range (r=0.9997), (correlation coefficient), percentage linearity (r^2 %=99.95). the proposed approach was compared to the previous technique (uv-spectrophotometric at λmax=273 nm). it can be concluded that, in addition to the technique's sensitivity (developed) and the use of a few chemicals, it outperforms the 10 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.
