Tetraethyl orthosilicate (TEOS, 98%, analytical reagent) was purchased from Acros Organics. Absolute ethanol (99.9%, analytical reagent) and ammonia water (NH4OH, analytical reagent) were obtained from Sigma Aldrich Co., St. Louis, MO, USA. To prepare patterned MIP films, MAA (Daejung Chemicals & Metals Co., Siheung, Korea) was used as a functional monomer. EGDMA, 2,4-dichlorophenoxyacetic acid (2,4-D; Mw 221.04 g/mol), and dimethylformamide (DMF) were purchased from Tokyo Chemical Industry Co (Tokyo, Japan). use as cross-linker, template molecule, and solvent, respectively. 2,2′-azobisisobutyronitrile (AIBN), used as an initiator, was purchased from Daejung Chemicals & Metals Co. Atrazine, ametryn, glufosinate (Sigma-Aldrich Co.), and (4-chloro-2-methylphenoxy)acetic acid (MCPA, Tokyo Chemical Industry Co.) were used as 2,4-D-analogous chemicals for the MIPs’ selectivity test. Deionized (DI) water (Pure & Ultra pure water system, pure ROUP30, Pure Water Co., Namyangju, Korea) and all other chemicals were used as received.

Methanol, acetone, and glacial acetic acid (HAC) were achieved from Sinopharm Chemical Reagent Co., Ltd. (Shanghai, China). 4-chloro-2-methylphenoxy acetic acid (MCPA), 2,4-dichlorophenoxyacetic acid (2,4-D), 2,4Dichlorprop (2,4-DP), 2,4dichlorophenoxybutyric acid (2,4-DB), and 2-(2,4,5-trichlorophenoxy) propanoic acid (2,4,5-TP), were purchased from ANPEL Laboratory Technology Inc. (Shanghai, China). For the standard solution of 100 μg⋅L -1 , five kinds of PCAs were dissolved in a 100 mL volumetric flask with Methanol and stored in 4 • C. A series of working aqueous solutions were obtained by diluting the standard solution with pure water.

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.
