Abstract:
Biochar is a carbon-rich material made from the combustion of biomass. It is a sustainable material
that can be used as a solid-phase extraction (SPE) sorbent, but conventional research uses energy-intensive
pyrolysis methods to produce this. A more energy-efficient approach, using a laser irradiation process, was
explored to produce a biochar sorbent for the SPE of organophosphorous pesticides (OPPs). Various biomass
materials, rich in lignin, were assessed to produce laser-induced biochar. From characterization data by Raman
spectroscopy, cork sheet was the most consistent and, hence, selected as the main biomass material. A central
composite design (CCD) was employed in optimizing the following lasing parameters: speed, power, and
number of lase times. Lasing speed was best at high settings (200-250 mm/s), and number of times lased was
optimal at 1 lase time. Power varied according to the physical properties and functionalities of the analyte.
OPPs that were non-polar and aromatic favored high power (10.5-12 W), while OPPs that are non-aromatic
favored low power (6-7.5 W). The optimized parameters that covered most OPPs were 9 W, 250 mm/s, and 1
lase time. This new application of laser-induced biochar shows the potential for low-energy production of a
biochar sorbent for solid-phase extraction.
