Key Points

To evaluate the efficiency of thiol-functionalized magnetic biochar for extracting heavy metals from environmental water samples.
Synthesis of thiol-functionalized magnetic biochar (MB-SH)
Application of magnetic dispersive micro-solid-phase extraction (MD-µSPE)
Coupling the extraction with inductively coupled plasma mass spectrometry (ICP-MS) for analysis
Testing with Pb(II), Cd(II), and Hg(II) in water samples
MB-SH showed a high adsorption capacity for Pb(II), Cd(II), and Hg(II)
Simultaneous determination of metals achieved with high recovery rates
ICP-MS confirmed the detection of heavy metals at low concentration levels
The method improved sensitivity and specificity for environmental monitoring

Implication

Demonstrates efficient heavy metal detection in environmental waters using a novel biochar sorbent, indicating potential improvements in water quality monitoring.

Abstract

A thiol-functionalized magnetic biochar (MB-SH) was synthesized and utilized as an efficient sorbent for magnetic dispersive micro-solid-phase extraction (MD-µSPE) coupled with inductively coupled plasma mass spectrometry (ICP-MS) for the simultaneous...
