2026-06-16 Dataset on Preparation-free Detection of Rice Using LIBS doi:10.57760/sciencedb.39408 en Heavy metal-contaminated rice grains were prepared using a solution immersion method. Laser-Induced Breakdown Spectroscopy (LIBS) was employed to acquire the spectral intensities of heavy metals in the rice grains. A subset of samples was selected for acid digestion to determine the reference heavy metal concentrations. A calibration model was established based on these measurements, and the remaining samples were preserved for subsequent rapid, preparation-free detection.
