MCPA (2-methyl-4-chlorophenoxyacetic acid) is a widely used phenoxy herbicide introduced in 1945. It selectively controls broad-leaf weeds in pasture and cereal crops . The mode of action of MCPA is as an auxin , which are growth hormones that naturally exist in plants.

2014年9月24日 · An outer-sphere complex and a monodentate inner-sphere complex with the neutral MCPA molecule were found to be the most energetically stable adsorbate forms. MD modeling predicted that the latter forms via the sharing of the carbonyl oxygen between the MCPA carboxylate group and a singly coordinated surface hydroxyl group, releasing an H 2 O ...

2024年3月15日 · MCPA (2-methyl-4-chlorophenoxyacetic acid) is a commonly used phenoxy herbicide that poses potential risks to aquatic life. In this study, we present an innovative analytical approach for MCPA quantification, employing molecularly imprinted polymers (MIPs) for selective extraction and ambient plasma mass spectrometry for direct on-line analysis.

2024年7月1日 · 2-Methyl-4-chlorophenoxyacetic acid (MCPA) is a herbicide that poses a threat to the environment. In this study, MIL-88A was utilized as a photocatalyst to degrade MCPA. Results demonstrated that the Light/MIL-88A/H2 O 2 system exhibited remarkable photo …

2022年10月15日 · Using MCPA as an agrochemical model, our results have confirmed the alteration of DOM complexation activity and gave a new mechanism under the chemodiversity perspective. Specifically, the complexation of DOM with MCPA was enhanced in VF and RV but slightly decreased in AL.

Adsorption characteristics of herbicide 4-chloro-2-methylphenoxyacetic acid (MCPA) have been evaluated using bituminous shale (BS) as a model adsorbent-containing solid organic matter in a...

In this study, MCPA imprinting polymer was obtained by precipitation polymerization using methacrylic acid (the functional monomer), ethylene glycol dimethacrylate (the cross-linker), 2, 2’-azobisisobutyronitrile (the initiator) and MCPA (the template molecule) in acetonitrile solution.

2020年7月17日 · Depending on a pH range, neutral or deprotonated MCPA species are anticipated to adsorb on protonated or neutral goethite surface. Neutral MCPA molecule can interact through the carbonyl oxygen and/or OH group of the carboxyl group (–COOH). The anionic MCPA form has two oxygen atoms of the carboxylate group available for the interaction.
