| Summary: | This paper reports the analysis of heavy metal from contamination soil using laser ablation technique. The soil samples were taken at various distances (200-1000 m) and depths (10-50 cm) from Port Dickson power station area in Negeri Sembilan-Malaysia. All samples were dried and pelletized prior to excitation. Calibration was carried out by injected pure powder of Pb into the soil matrix. A Q-switched Nd:YAG laser was employed to ablate the sample. Maya spectrometer with resolution of 0.2 nm was utilized to record the emission spectrum of fluorescence beam. The quantitative results of laser induced breakdown spectroscopy (LIBS) technique were validate via flame atomic absorption spectroscopy (FAAS) analysis which shown in a good agreement. The detected heavy metal element of lead also identified to be lower than the threshold limit set by DOE and Europe standard and yet the studied area is established to be among the lowest pollutant area in worldwide. |
