in this work， a highly sensitive electrochemical sensor based on Zn-doped copper gallium oxide@ordered mesoporous carbon (Zn-CuGaO2@CMK-3) for signal amplification was successfully developed for the simultaneous detection of sun.e. yellow （SY） and tartrazine （TZ） in foods. Compared with CuGaO2@CMK-3， Zn-CuGaO2@CMK-3 offered enhan.e. conductivity and catalytic properties owing to the improved carrier density， which was beneficial to the electrooxidation of SY and TZ. Un.e. the optimal testing conditions， the constructed Zn-CuGaO2@CMK-3/GCe sensor offered a wide linear con.e.tration ran.e.（0.25 to 100.00 μmol/L） for the detection of both SY and TZ. The limits of detection for SY and TZ were 0.044 μmol/L and 0.059 μmol/L， respectively. Recovery experiments were performed in milk， white vinegar and biscuit samples， yielding satisfactory recoveries （82.70%-114.80%）. Furthermore， the sensor was successfully applied to the determination of the SY and TZ residues in two kinds of carbonated drinks， and the results were nearly consistent with those detected by the high performan.e.liquid chromatography （HPLC） method （P＞0.05）.

Organophosphorus pesticides (OPPs) in foods pose a serious threat to human health， motivating the development of novel analytical methods for their rapid detection and quantification. A magnetic covalent organic framework (M-COF) adsorbent for the magnetic solid-phase extraction (MSPe) of OPPs from foods was reported. M-COF was synthesized by the Schiff base con.e.sation reaction of 1，3，5-tris (4-aminophenyl)ben.e.e and 4，4-biphenyldicarboxaldehyde on the surface of amino-functionalized magnetic nanoparticles. Density–functional theory (DFT) calculations showed that adsorption of OPPs onto the surface of M-COF involved hydrophobic effects， Van der Waals in.e.actions， π–π in.e.actions， halogen-n bonding， and hydrogen bonding. Combined with gas chromatography–mass spectrometry (GC–MS) technology， the MSPe method features low limits of detection for OPPs (0.002–0.015 μg/L)， good reproducibility (1.45%–6.14%)， wide linear detection ran.e.(0.01–1 μg/L， R≥ 0.9935)， and satisfactory recoveries (87.3%–110.4%). The method was successfully applied for the trace analysis of OPPs in spiked fruit juices.
