Isoproturon is a phenyl urea-derived systemic herbicide used widely for pre- and post-emergence control of annual grasses and broad-leaved weeds for wheat, barley, and rye. This selective herbicide is absorbed by roots and leaves and inhibits the electron transport in photosystem II (PS II) by binding to the D1 protein in the thylakoid membrane.

Isoproturon has been detected worldwide in soil, groundwater, surface water, or even in drinking water, exceeding the threshold value of 0.1  μg L⁻¹, as a result, the European Union (EU) decided to ban its use in 2016. The EU has classified it as a priority micro-pollutant and has regulated its maximum residue level (MRL) at 0.3  μg L⁻¹ for inland surface waters.

アプリケーション

It is intended to be used as a certified reference material (CRM) for calibration in chromatography and other analytical techniques. Isoprocarb CRM may also find its use as described below:

• To elucidate the effect of isoproturon on the growth, physiological, and biochemical responses of wheat (Triticum aestivum)
• To develop a molecularly imprinted polymer (MIP) based glassy carbon electrode for the electrochemical detection of isoproturon in water
• To conduct a physicochemical pre-treatment for the photocatalytic destruction of metobromuron and isoproturon by different advanced oxidation processes (AOPs) in a small batch photoreactor and under direct sunlight
• To investigate the degradation of isoproturon using Trametes versicolor laccase and its laccase-mediator systems and study the influence of the operational parameters (pH, temperature, metal ions, and PEG) on the degradation process
• To study the effect of pH and the role of organic matter in the adsorption of isoproturon on three different types of soils and on quartz as natural adsorbents
