A new “capturer” for electrochemical detection of organophosphate pesticides: The hydroxylation and carbonylation carbonaceous nanospheres

摘要

The hydroxylation and carbonylation carbonaceous nanospheres (H/C-CNSs) were used in electrochemical detection of organophosphate pesticides (OPs) for the first time. H/C-CNSs were proven as a new sorbent for solid-phase extraction of OPs without the need for an external modification. Under the optimized conditions, OPs, such as methyl parathion, ethyl parathion, fenitrothion, and paraoxon, could be detected by differential pulse voltammetry (DPV) without any interference from other aromatic derivatives, showing a superior selective performance...
