Diniconazole, hexaconazole, and imazalil were obtained from Aladdin (Shanghai, China); β-CD, HP-β-CD, and 2-HP-γ-CD were purchased from Aladdin; C12H25SO4Na (SDS), Na2HPO4, Na2B4O7.10H2O, NaOH, H3PO4, and methanol were obtained from Sinopharm Chemical Reagent (Shanghai, China). All experimental water was purified by a Milli-Q apparatus (Millipore, Bedford, MA, USA). All samples and background solutions were filtered by a 0.22 μm nylon filter (MSI, Westboro, MA, USA) and degassed by sonication.
Background electrolyte was prepared by dissolving Na2B4O7.10H2O in ultrapure water to 100 mM. The running buffer was prepared by dissolving CD and SDS in the background buffer and adjusting the pH of butter with NaOH or H3PO4. All buffers were filtered through a 0.22 μm filter before use. Stocking solutions of signal chiral antifungal pesticides were prepared in methanol at a concentration of 2000 μg/mL and stored at 4°C. Working solutions were prepared by diluting the stocking solutions with a background buffer to a suitable concentration. All samples were filtered before sampling.

The chemicals (including HA, NaHCO3, Na2CO3, Na2B4O7·10H2O, and AlCl3·6H2O) were all purchased from Sinopharm Chemical Reagent Co. Ltd., Beijing. All reagents used were of analytical grade and deionized water was used to prepare all solutions. AgNP powder was purchased from Nanjing XFNANO Materials Tech. Co. Ltd. Its purity and specific surface area were 99.9% and 3 m2 g−1, respectively.
The HA stock solution (1 g L−1) was prepared by dissolving 1.0 g of HA in sufficient deionized water and adding 4.2 g of NaHCO3 to provide a certain buffer capacity and ionic strength. The solution was stirred continuously for 2 h and then diluted to 1 L. The AgNP dispersion was prepared by dissolving 50 mg of AgNPs in 1 L deionized water followed by ultrasonic treatment for 1 h to guarantee the complete dispersion of AgNPs. The synthetic AgNP–HA water contained 10 mg HA and 5 mg AgNPs per liter. In addition, 5 mM L−1 borate buffer was added to prevent silver ion release. The properties of this water are as follows: turbidity = 32.5 ± 0.7 NTU, pH = 8.40 ± 0.05, DOC = 5.629–5.412 mg L−1 and zeta potential = −14.8 ± 0.4 mV.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
