Quantitative Analysis of Mn in Soil Based on Laser-Induced Breakdown Spectroscopy Optimization
This paper uses laser-induced breakdown spectroscopy and support vector machine to analyze the content of Mn in soil. Forty-four soil samples were collected in Huaibei, Anhui. The samples were divided into training set (34 samples) and test set (10 samples) using Kennard-Stone (K-S) method. Multiple linear regression (MIR), grid search method (GSM), genetic algorithm (GA), particle swarm optimization (PSO), and least squares method (LS) were used to establish quantitative analysis models. The results show that the correlation coefficients
