  imidacloprid
Determination of the Insecticide Imidacloprid in Potato (Solanum tuberosum L.) and Onion (Allium cepa) by High-Performance Liqui
      
A high-performance liquid chromatography (HPLC) method has been proposed for the determination of imidacloprid residues in fortified potato (Solanum tuberosum L.) and onion (Allium cepa) and in treated potato and onion samples.
      
Sample preparation consisted of dichloromethane extraction of imidacloprid from the plant material, followed by purification of the obtained onion extract on an LC-Florisil disposable cartridge.
      
The HPLC-diode-array-detection (DAD) method has been developed on reversed phase for separation of imidacloprid with isocratic elution with a mixture of 0.01 M phosphate buffer (pH 3.15) and acetonitrile (75 : 25, v/v).
      
Spectral data obtained with DAD allow the identification of imidacloprid residue.

The photolysis, hydrolysis of imidacloprid in three buffer solutions with different pH values and the degradation of imidacloprid in Northeast China black soil, Jiangsu Taihu paddy soil and Jiangxi red soil were studied in laboratory. The results of the study show that the photochemical reaction of imidacloprid in aqueous solutions irradiated by 300 W low voltage mercurial lamp fitted to the first order dynamic equation, and its photolysis half life was 6.81 h.

在实验室测定了吡虫啉的光解、不同pH条件下的水解与在东北黑土等3种不同土壤中的降解。试验结果表明,在300W低压汞灯下,吡虫啉水相溶液的光解呈一级反应动力学反应,光解半衰期为6.81h;在pH5、pH7、pH9的缓冲溶液中的水解半衰期分别为30.6、13.6与8.0d;在东北黑土、太湖水稻土和江西红壤中的降解半衰期分别为10.7、11.1和4.1d。

TiO 2 catalysts adhered to the glass were used for investigating photocatalytic degradation of pesticide imidacloprid in aqueous solution under 3×8W fluorescent lamps.The results showed that the photocatalytic degradation rate of imidacloprid was high and up to above 50%.And the photolysis fit a first order kinetic relationship well.The photolysis rate constant of imidacloprid decreased with increasing initial concentration,which was explained by two mechanisms of photocatalytic degradation.By contrast,adherent TiO 2 films with adding Carboxymethyl Cellulose Na to treat was not easy to take off and the catalytic activity would not drop.In addition,the feasibility the imidacloprid photocatalytic degradation under the sunlight was also studied.

以主波长365nm的黑炽荧光灯为光源,研究了由CMC-Na附载TiO2光催化降解咪蚜胺农药的过程。结果表明,咪蚜胺农药在3×8W黑炽荧光灯照射下,经附载TiO2作用3h后可降解50%以上,其光解可用假一级动力学方程表示。对于加CMC-Na附载的TiO2玻板,TiO2不易脱落,经多次使用其光催化活性不变,而直接附载的TiO2却有流失现象发生。另外,初探了以自然光为光源催化降解咪蚜胺农药的可行性。

Kinetics of imidacloprid hydrolysis were studied at various pH values.The experimental results show that imidacloprid is stable in acid and neutral water and its hydrolysis easily takes place in basic water.By extracting and analyzing hydrolysis products,it was found that the primary hydrolysis product is 1 [(6 chloro 3 pridinl)methyl] 2 imidazolidone.The hydrolysis mechanism of imidacloprid is thus proposed.

介绍了吡虫啉在不同酸、碱条件下的降解动力学情况.实验表明,吡虫啉在酸性、中性条件下比较稳定,不易水解,而在碱性条件下水解速度较快.通过对水解产物的鉴定,确定了水解产物主要是1(6氯—3吡啶甲基)—2咪唑酮,从而推测了有关吡虫啉的水解机理.
