Laser-induced biochar as a miniaturized sorbent for μSPE of organophosphorus pesticides from environmental waters
Micro-solid phase extraction (μSPE) has been applied for sample preparation steps in trace analysis. The development of μSPE is trending toward miniaturization through a reduction in device dimensions, a decrease in sorbent amounts, and/or an incorporation of micro-sized or nano-sized materials. Various materials, both synthetic and organic in source, have been used as sorbents. Biochar, …
