چکیده انگلیسی
In the present paper, LIB spectra of different water samples having varying concentration of Cr (certified reference material, CRM) have been recorded by using liquid jet (fabricated in our laboratory) configuration. Calibration curves for different atomic lines of Cr are compared and it is found that calibration curve for Cr II (283.5Â nm) atomic line is the best in terms of the Limit of detection (LOD) which is found to be 30Â ppm. This calibration curve has been used for quantification of Cr in wastewater collected from Cr-electroplating industry where the concentration of Cr is found to be 1500Â ppm. Its removal can be planned by biological system, which is in progress.
