Title: An approach to determine the efficiency of LIBS system in aqueous solution using optical instruments
Abstract: Laser induced breakdown spectroscopy (LIBS) has been applied to determine its Limit of Detection (LOD) in aqueous solution. It was based on only one single-pulse laser system where we used a wood slice as the liquid absorbent to make over liquid sample analysis using the technique of LIBS. Using this approach, it is obvious to achieve good reproducibility and high detection sensitivity. More than twenty readings of the background emission were taken to calculate the LOD. The calculated value of the background intensity (σ) was 42.435 and the value of the gradient (S) of the calibration curve of Pb element in aqueous solution fitted with straight line through origin was 178.57 mg-1L. The LOD was determined and its experimentally calculated value in our study was 712ppb(parts per billion) with orders better than those determined by directly analyzing liquid samples focusing the laser light on a liquid surface In addition, the wood slice is very uncomplicated to handle and this study provides a more sensible approach for rapid and susceptible metal component investigation in aqueous solutions using laser induced breakdown spectroscopy, which is really functional in various fields to analyze metal elements in aqueous solution, especially for monitoring toxic grave metals in aqueous solution.
Key Words: LIBS, Atomic emission Spectroscopy, Liquid absorbent, Background intensity and Toxic grave metals
