An international team of researchers (Russia, China, Czech Republic, South Korea) created a sorbent that belongs to metal-organic frameworks, for imidacloprid insecticide removal from water. They developed a method to synthesize a metal-organic framework named UiO-66 with zirconium ions. The framework is sensitive to imidacloprid and due to its porosity and physicochemical properties, it attracts insecticide molecules removing them from water. In tests effective water purification took 15 grams of sorbent per liter. The sorbent may be reused several times. They reached up to five cycles during experiments. In the future the sorbent can be used in filtration systems, for instance, at agricultural enterprises. Due to larger particles, the throughput of the sorbent is higher, and liquids penetrate easier…read more. TECHNICAL ARTICLE
