Abstract:
We successfully developed a fast detection system based on orthogonal dual-pulsed laser-induced breakdown spectroscopy (DP-LIBS) to characterize the level of a new low-cost adsorbent material prepared from date palm kernel pits. The activated carbon (AC) was produced from different heated and chemically treated date palm kernel pit samples to be used as adsorbent material for the removal of some pollutants from wastewater. The quantitative, as well as qualitative analysis, was performed using the DP-LIBS analytical technique. Hence, the valuable elements like the carbon present in the date palm kernel pits was perfectly recognized. The registered spectra of the sample cover the spectral lines of carbon. The quantitative analysis of carbon, carried out in different samples of date palm kernel pits, using DP-LIBS revealed that the estimated limit of detection of carbon in these samples is about 225.19 mg/L. The precision of DP-LIBS data for determining the concentration of activated carbon element present in the date palm kernel pits was validated via the inductively coupled plasma-optical emission spectrometry (ICP-OES) as a standard technique.
