Abstract

Abstract

In order to develop an adsorbent with high efficiency and selectivity for long-lived activation products in radioactive liquid waste, metal-organic frameworks (MOFs) material ZIF-67 was prepared at room temperature, and the thermal stability test and structural characterization of the material were carried out. The influence of the initial pH values, adsorption time and initial concentration of the solution on the adsorption of Co(II) and Mn(II) by ZIF-67 was investigated for the first time. The results show that ZIF-67 is a microporous material with good hydrothermal stability. Under the conditions of pH=6.0, temperature of 30℃, and initial concentration of 500 mg/L, the saturated adsorption capacities of ZIF-67 for Co(II) and Mn(II) reached 305.63 mg/g and 197.43 mg/g, respectively. ZIF-67 has adsorption selectivity for Co(II), Mn(II) and Ni(II) in mixed metal ion solution. Therefore, ZIF-67 has a good application prospect in the treatment of activation products in actual radioactive liquid waste.
