Description

technical field

[0001] The invention belongs to the technical field of pesticide detection, in particular to a Tb-GMP / CeO 2 Composite material and its preparation method and detection method of zirdine. Background technique

[0002] Zirbane is a widely used dithiocarbamate fungicide for the prevention of fungal diseases in seeds and crops. At present, the standard detection method for ziram residues in agricultural products in my country is gas chromatography. In the gas chromatographic determination of ziram, it is necessary to heat zirdine under strong acidic conditions at a high temperature to convert it into carbon disulfide, and then determine the carbon disulfide by gas chromatography to realize the indirect determination of ziram content. This indirect method for the determination of ziram is cumbersome, time-consuming, and requires the use of strong acids, which does not conform to the principle of green chemistry to reduce the use of dangerous goods. In addition,...
