Laterite is a geol. formation in tropical and subtropical regions with high iron and aluminum content.It is extensively used in cement production, water filtration, and the formation of geopolymers.The optical emission spectrum of laterite confirmed the presence of Ca, Al, Si, Mg, Fe, K, Li, Ti, Cu, Sr, Na, Ni, Mn, Rb, Ba, O, H, and N.CF-LIBS was employed to determine the relative elemental concentrationThe quant. results encounter a significant challenge due to self-absorption, resulting in a nonlinear relationship between the emission signal and concentrationThe escape factor method, which numerically determines the fraction of radiation escaping the plasma without reabsorption, is an effective approach for correcting self-absorption.The escape factor, determined by optical thickness and spectral line shape, was incorporated in the equation of spectral line intensity to correct for self-absorption.This correction in emission intensities ensures a strong linear and reliable correlation with concentrationBoltzmann and Saha-Boltzmann plots were constructed to estimate the plasma temperatureThe determined relative elemental concentration using one-line CF-LIBS was compared with the results obtained by inductively coupled plasma mass spectrometry (ICP-MS).The comparative study of relative elemental concentrations illustrates significant improvement in CF-LIBS using the escape factor.
