摘要： A method for regulating the distribution of metallic nanoparticles within the resin support is provided. This method uses the ion exchange or absorption resin bearing basic functional groups as the support; firstly introducing the metal in the form of anionic complexes onto the resin support through the ion exchange process, then realizing the purpose of regulating the distribution of the metal and its compound within the resin support by means of changing the concentration of the reductive or deposition agent in water solution and the reaction time. The regulated distribution of metallic nanoparticles within the resin support is in the form of rings with different depths and densities. The different distribution patterns result in improvements upon properties of the inorganic-organic composite material, such as reaction activity, reaction selectivity and metallic stability, and has significant referential value for preparation and structural regulation of other inorganic-organic composite materials of the same kind.

摘要： A deep purification method for removing trace thallium in water by using polymer-based nanosized manganese oxide is disclosed. This method comprising the following steps: adjusting the pH value of the water polluted with trace thallium to 5-8.5 and filtering it, then channeling the water so treated through a packed tower of filtering bed packed with polymer-based nanosized manganese oxide so that the thallium in water can be selectively adsorbed upon the nanocomposite material, stopping the adsorption process when the thallium in water reaches the leak point, and then using mixed solution of HCl—Ca(NO3)2 or NaOH—NaClO as the desorption agent and starting desorption and regeneration process for the packing material of polymer-based nanosized manganese oxide. This effectively reduces the concentration of thallium in water from 0.01-0.5 mg/L to lower than 0.1 μg/L, despite the much higher concentration of coexisting competitive cations such as Ca2+, Mg2+, Na+ and Si(IV).
