Chelating Polymers

The rapidly increasing demand for technologies aiming to resolve challenges of separations and environmental protection causes a sharp increase in the demand for ion exchange (IX) and chelating polymers. These unique materials can offer target-selective adsorption properties vital for the removal or recovery of harmful and precious materials, where trace concentrations thereof make other techniques insufficient. Hence, recent achievements in syntheses of IX and chelating resins designed and developed in our research group are discussed within this mini-review. The aim of the present work is to reveal that, due to the diversified and unique physiochemical characteristics of the proposed materials, they are not limited to traditional separation techniques and could be used in multifunctional areas of applications, including catalysis, heat management, and biomedicine.

Modified Zeolites

A series of Beta, ZSM-5 and MCM-22 zeolites modified with metal ions (such as Fe 3+ , Co 2+ , Ce 3+ , Ni 2+ and Cu 2+ ) for catalytic decomposition of N2O were prepared by using wet ion exchange method. The effects of different metal ions, the contents of metal ions and silicon aluminum ratio on catalytic decomposition activities of N2O were investigated, respectively. The results indicated that Beta with a SiO2/Al2O3=30 and 1% Fe 3+ have better catalytic decomposition activities to N2O, the completed catalytic decomposition temperature to 35% N2O in the condition of 4000 h-1 GVSH is 350 0 C.
