Example Embodiment
[0034] Example 1
[0035] (1) Preparation of sulfonated calix[4]arene modified nano silver sol
[0036] At room temperature, take 2mL of 10 -2 mol / L silver nitrate solution was added to 96ml of double distilled water and 2ml of 10 -2 mol / L sulfonated calix[4] arene aqueous solution, stirred for 20 minutes. Then, 8.8 mg of sodium borohydride was added, and stirring was continued for 5 minutes, so that the sulfonated calix[4]arene modified nano-silver sol was prepared.
[0037] Colorimetric detection of sulfonated calix[4]arene modified nano-silver sol for hydrocarbophos:
[0038] 0.5mL different concentrations (10 -3 -10 -7 mol / L) hydrocarbophos was added to 2 mL of sulfonated calix[4]arene modified nano-silver sol and mixed uniformly. After 10 minutes, the color of the solution changed from yellow to red.

[0039] Example 2
[0040] (1) Preparation of sulfonated calix[4]arene modified nano silver sol
[0041] At room temperature, take 2mL of 10 -2 mol / L silver nitrate solution was added to 96ml of double distilled water and 2ml of 10 -2 mol / L sulfonated calix[4] arene aqueous solution, stirred for 20 minutes. Then, 4.4 mg of sodium borohydride was added, and stirring was continued for 5 minutes, so that the sulfonated calix[4]arene modified nano silver sol was prepared.
[0042] Colorimetric detection of sulfonated calix[4]arene modified nano-silver sol for hydrocarbophos:
[0043] 0.5mL different concentrations (10 -3 -10 -7 mol / L) hydrocarbophos was added to 2 mL of sulfonated calix[4]arene modified nano-silver sol and mixed uniformly. After 10 minutes, the color of the solution changed from yellow to red.
