Embodiment
The preparation of standard solution:
Accurately take standard sample of pesticide in 100mL volumetric flask, be diluted to scale by suitable solvent, obtain pesticide standard storing solution for subsequent use.
Pesticide standard working solution is diluted obtained by above-mentioned standard solution.
Leaching is tested:
The preparation of I earth pillar: take through air-dry, grind, Taihu Lake rice soil, black soil of Northeast China and the Red Soil about 600 grams of sieve (20 order), fill out post 5cm × 30cm, above soil layer, add the thick moral silica sand of 1cm, add 0.01mol/L calcium chloride solution in post to soil saturation water holding capacity.
II dosing: 1.0mg clothianidin agricultural chemicals is evenly dripped in earth pillar upper strata quartz sand layer.
III earth pillar drip washing: add the drip washing of CaCl2 solution with the speed of 30mL/h, counts 10 hours 300mL (being equivalent to rainfall 150mm/h), collects and drenches fluid.
IV soil sample measures: earth pillar is evenly cut into 6 sections, the clothianidin content measuring each section of soil respectively and drench in fluid.
Sample extraction method:
Adopted soil-like proceeded in 150mL tool plug ground Erlenmeyer flask, add 50mL × 2 acetone, at 25 DEG C after constant temperature oscillation 0.5h, high speed centrifugation is separated, and by supernatant liquid filtering in triangular flask, merges extract, through Rotary Evaporators evaporate to dryness acetone.Pour in 250mL separating funnel, use 40mL ethyl acetate oscillation extraction 2 times respectively, merge organic phase, through Rotary Evaporators evaporation and concentration to certain volume, for liquid chromatogram measuring.
The evaluation of pesticides
The mensuration of agricultural chemicals can select gas chromatography, liquid chromatography etc. to be applicable to the Instrument measuring of this agricultural chemicals.
Interpretation of result
Test findings (see table 1) shows, when leaching liquor is 300mL, in different earth pillar, clothianidin has obvious movement.The position of Red Soil concentration maxima appears at 20.0 ~ 25.0cm place, and Taihu Lake rice soil concentration maxima is 5.0 ~ 10.0cm place, and the movability of black soil of Northeast China is slightly poor, and Cmax value appears at 0 ~ 5.0cm place (see table 6-2).Red Soil drenches in fluid can detect clothianidin agricultural chemicals, and drenching fluid Pesticides proportion is 56.0%.And do not detect in Taihu Lake rice soil and black soil of Northeast China pouring fluid.Show that the movability of clothianidin in Red Soil will obviously be better than Taihu Lake rice soil and black soil of Northeast China.
The distribution of table 1 clothianidin in different earth pillar
The pesticide concentration of clothianidin in different soil is in table 2.As shown in Table 2, in Red Soil earth pillar, 0 ~ 10cm section pesticide volume accounts for 0.95% of total amount, and Taihu Lake rice soil 0 ~ 10cm section accounts for 71.31%, and northeastward in black earth 0 ~ 10cm section account for more than 92.33%.
The leaching of clothianidin in above-mentioned soil has larger difference, and wherein leaching speed order is: Red Soil > Taihu Lake rice soil > black soil of Northeast China.This and the clothianidin solubleness in water comparatively large (340mg/L), adsorption by soil are more weak relevant, consistent with adsorption test result.For molecule-type agricultural chemicals, the content of its leaching characteristics in soil and the soil organism is inverse correlation relation.The above results describes this argument preferably.
The number percent of table 2 clothianidin in different soil (%)
