Abstract:
A process for the production of dual-functional ion exchange resins from lignocellulosic agricultural material involving anionization of the lignocellulosic agricultural material with citric acid and then cationization of the lignocellulosic agricultural material with dimethyloldihydroxyethylene urea (DMDHEU) and choline chloride, or cationization of the lignocellulosic agricultural material with DMDHEU and choline chloride and then anionization of the lignocellulosic agricultural material with citric acid.
