Latest Patents

Jun Xu holds a patent for the "Method of preparation and application of ion-keeper adsorbent." This invention provides a method for preparing and applying an ion-keeper adsorbent by adjusting the pH for selective oxidation. The process involves the oxidation of ferrous iron into ferric iron, followed by the separation of iron after a hydrothermal reaction. The adsorbent is prepared using biomass as raw materials, resulting in materials with internal rules, hierarchical pores, and high selectivity. This technology is particularly useful for the deep purification of chromium solutions, effectively removing impurities such as iron, aluminum, and vanadium. The process culminates in the production of high-purity chromium products, thereby achieving the recycling and comprehensive utilization of waste resources.
