Abstract
Laser Induced Breakdown Spectroscopy (LIBS) has been introduced as a type of analytical equipment to determine elements on the surface of various materials. In this study, standard and sample soils were molded to make a pellet for LIBS analysis. The soils were also digested with acids for ICP analysis. Accuracies ranging between 86.5% and 119.9%, an RSD of 12.3%, an LOD of 6.09 mg/kg, and an LOQ 19.41 mg/kg resulted from the analysis of copper in soils using LIBS. Correlations (R2) of LIBS with ICP-aqua regia digestion and with ICP-total digestion analysis concentrations were over 0.96 for 28 samples. The total analytical time for the LIBS method was 385 min, which was 43.4% shorter than for the ICP-OES method (680 min). For the analysis of copper in soils, LIBS can be used for on-site detection without chemical preparation.
