چکیده
Human activity today produces a large number of pollutants that end up in the environment, such as soil, water, and airborne particles. The first objective this work is to introduce new third-order multivariate calibration approach called self-weighted alternating quadrilinear decomposition (SWAQLD) for analysis organic pollutant fluorene (FLU) different water systems. One simulated two real four-way data sets are used study potential proposed comparison with classical algorithms, namely (AQLD) parallel factor (PARAFAC). results show SWAQLD inherits advantages PARAFAC terms not only tolerance experimental noise but also fast convergence certain robustness overestimation rank models from AQLD. second propose way generating using excitation–emission matrix phosphorescence (EEMP) at room temperature kinetic process oxidation FLU complex chemical obtained rate constant half-life oxidation, on average, 0.015 min−1 45.5 min free-interference 0.017 40.0 wastewater, respectively. Research coupled EEMP allows quantification monitoring analytical conditions complexities excellent choice model components.
