Abstract Fluorescence excitation‐emission matrix (EEM) measurements are useful in fields such as food science, analytical chemistry, biochemistry and environmental science. EEMs contain information which can be modeled using the parallel factor analysis (PARAFAC) model but data is often complicated due to both Rayleigh Raman scattering. There several established ways deal with scattering effects. However, all of these methods have associated problems. This paper develops a new method for...
In this study the degradation of Methyl Orange, using Fenton reaction was studied and optimized central composite design as a response surface methodology. The effects various experimental parameters in were investigated design. 28 experiments, with 4 factors 5 levels for each factor designed. These (or variables) were: initial concentration Fe (II), H2O2, oxalate time. A full-quadratic polynomial equation between percentage dye (as response) established. After removing non-significant...
Abstract Nowadays, the use of natural wastes and adsorbents along with their modification by simple new methods based on metal oxides to remove dye pollutants has been focus many researchers. In this study, for first time, low-cost eggshell (EGS) tungsten oxide (WO 3 ) photochemical method as a green, ultra-fast, cost-effective, biodegradable adsorbent is reported methylene blue (MB) pollutant. The EGS modified WO was investigated EDX, EDX mapping, XRD, FE-SEM, UV–Vis Diffuse Reflectance...
The accurate and selective determination of morphine in biological pharmaceutical samples remains a critical challenge due to matrix interferences the need for highly sensitive detection methods. While traditional techniques such as GC-MS, HPLC-UV, LC-MS/MS offer high sensitivity selectivity, they often require complex sample preparation, expensive instrumentation, extensive calibration procedures. In this study, we employ rank annihilation factor analysis (RAFA) combination with kinetic...
