  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.

Imidacloprid,which is a novel insecticide,showed≥98% insectical efficiency against aphids (peach aphid,cottonaphid and wheat aphid etc.)at the dosage of 0.015kg a. i./ha. The fast effect and residual effect were better than that offenvalerate obviously in the field test.

吡虫啉是一种新型杀虫剂,每亩用纯药1克对桃蚜、棉蚜和麦蚜等蚜虫的防效都在98%以上,且速效性和持效性都明显地优于氰戊菊酯。

The control effects of 8 insecticides to Melanographia flexilineata are reported in this paper.The results showed that the control effects of imidacloprid,carbosulfan,quinalphos,diflubenzuron,flufenoxuron were all over 90%.Deltamethrin also had good effect.The effects of omethoate and dichlorvos were not as good as expected.

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。
