Limited methods exist to determine the composition of particle mixtures. This research presents a simple UV-vis-spectroscopy-based method for separate quantification particles mixtures considering following: synthesized ferrihydrite, commercial Fe2O3, and natural allophane. Calibration curves adsorption/scattering coefficients are determined each at different wavelengths. is main input solve equation systems and, ultimately, quantify concentration in binary The limit detection varies with wavelength type, yielding values as low 1.5, 0.2, 1.6 mg L−1 ferrihydrite (500 nm), Fe2O3 (450 allophane respectively. study provides simple, low-cost straightforward method, compared atomic-spectroscopy- or chromatography-based techniques, resolving suspension.
