Embodiment 1
[0034] This example provides a preparation method of a pesticide slow-release agent. The method first modifies wheat straw with phytic acid, and then adsorbs the pesticide onto the phytic acid-modified wheat straw, which specifically includes the following steps:
[0035] Step 1, wheat straw pretreatment: clean the wheat straw, dry it at 50°C, crush it into 100-200 mesh powdered wheat straw, then wash the wheat straw powder with distilled water, then filter, and filter the filtered material with 0.1mol / Soak and stir in L hydrochloric acid for 2 hours in the greenhouse for acidification, then ultrasonically wash for 30 minutes (40 kHz, 300 W), filter, wash with absolute ethanol until neutral, and dry at 50 ° C to obtain pretreated wheat straw. Optical microscope characterization of wheat straw powder figure 1 As shown, the scanning electron microscope characterization of wheat straw powder is shown in figure 2 shown.
[0036] Step 2, preparation of phytic acid modified whea...
Embodiment 2
[0042] This example provides a preparation method of a pesticide slow-release agent. The method first modifies wheat straw with phytic acid, and then adsorbs the pesticide onto the phytic acid-modified wheat straw, which specifically includes the following steps:
[0043] Step 1, wheat straw pretreatment: same as Step 1 of Example 1.
[0044] Step 2, preparation of phytic acid-modified wheat straw: same as Step 2 of Example 1.
[0045] Step 3, preparation of imidacloprid pesticide slow release agent: same as Step 3 of Example 1.
[0046] The concentration of imidacloprid in the filtrate was measured by ultraviolet-visible spectrophotometer, and the adsorption amount of imidacloprid on phytic acid modified wheat straw was calculated. The results are shown in Table 1.
[0047] Determination of sustained release of imidacloprid pesticide sustained-release agent: Accurately weigh 0.1g of imidacloprid pesticide sustained-release agent, add it to 100mL deionized water with a pH va...
Embodiment 3
[0049] This example provides a preparation method of a pesticide slow-release agent. The method first modifies wheat straw with phytic acid, and then adsorbs the pesticide onto the phytic acid-modified wheat straw, which specifically includes the following steps:
[0050] Step 1, wheat straw pretreatment: same as Step 1 of Example 1.
[0051] Step 2, preparation of phytic acid-modified wheat straw: same as Step 2 of Example 1.
[0052] Step 3, preparation of imidacloprid pesticide slow release agent: same as Step 3 of Example 1.
[0053] The concentration of imidacloprid in the filtrate was measured by ultraviolet-visible spectrophotometer, and the adsorption amount of imidacloprid on phytic acid modified wheat straw was calculated. The results are shown in Table 1.
[0054] Determination of sustained release of imidacloprid pesticide sustained-release agent: accurately weigh 0.1g of imidacloprid pesticide sustained-release agent, add to 100mL deionized water with adjusted p...
