With accelerated industrial development and serious environmental issues, removing heavy metal ions from industrial discharge effluents is a significant subject. In the present paper, a novel absorbent polyvinylidene fluoride (PVDF) composite membrane based on β-cyclodextrin and zeolitic imidazole skeleton-8 (β-CD@ZIF-8) nanoparticles was prepared through the deep-permeation method. The nanoparticles are assembled in situ in PVDF membrane pores and anchored in each membrane pore along the membrane thickness direction. The batch adsorption experiment and characterization anal. were conducted to further investigate the performance of the composite membrane for the removal of Pb2+ and Cu2+ from wastewater. The results showed that the saturation adsorption capacities of β-CD@ZIF-8/PVDF micro membrane adsorbers for Pb2+ and Cu2+ were 708.130 and 651.379 mg/g, resp., which were remarkably higher than those of powder materials of β-CD@ZIF-8 and other porous materials due to the intensified contact within the confined space and more active sites provided within the membrane pores. The novel absorbent membrane behaved with excellent absorption capacity, demonstrating the tremendous potential for industrial applications. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Product Details of 20427-59-2).
Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. The evolution of transition metal catalysts has attained a stage of civilization that authorizes for an extensive scope of chemical bonds formation partners to be combined efficiently. Copper nanoparticles can catalyze the Ullmann coupling reaction in a wide range of applications.Product Details of 20427-59-2
