摘要

The invention relates to an organic material, which comprises a polymeric solid carrier, on which the grafted molecules conform to the following general formula () I, wherein M = 0, 1 or 2.R1 and R2 = a hydrocarbon group,Saturated or unsaturatedLinear or branchedC6-C12;R3=H;hydrocarbonSaturated or unsaturatedLinear or branchedC1-C12;hydrocarbonSaturated or unsaturated1. Contain one or more c3-c8 cycles;Or aryl, including one or more cycles;-Or R2 and R3 together form a group ("CH2"), n = 1-4;R4 = hydrocarbonSaturated or unsaturatedLinear or branchedC2-C8;hydrocarbonSaturated or unsaturated1. Including one or more cycles;1. Aromatics, including one or more cycles;Et-r5 = one hydrocarbon group,Saturated or unsaturatedLinear or branchedC3-C12;hydrocarbonSaturated or unsaturated1. Including one or more cycles;Or a hydrocarbon containing an aryl group consisting of one or more cycles, wherein R5 is connected to at least one group G, R5 is connected to a polymeric solid carrier (formed by pointill lines) by at least one covalent bond, and is selected from amido, alkenyl, alkyl, amine, thioether, Ether oxide and 1,2,3-triazole The invention also relates to the use of organic materials in the extraction of uranium ("VI") d from acid aqueous solution, the extraction and recovery methods of related uranium ("VI") and the precursor molecules of organic materials.
