The Synthesis Of Mesoporous Zirconium Organophosphonates With Cation Frameworks And Their Adsorption Of Acid Deystuff

Mesoporous organophosphonates materials have attracted much attentions on the applications in the fields of catalysis, separation and adsorption, immobility of biological molecules for their unique structural tailor and profuse chemical surface properties. In this work , we have devoted effort toward hydrothermal synthesis of the mesoporous organophosphonates materials by using organophosphonic acid ligands DPPA with ZrCl4 building units to obtain possible new types of mesoporous zirconium organophosphonates with cation frameworks and their Adsorption of Acid dyestuff. The synthesized materials were characterized by nitrogen adsorption-desorption measurements,SEM,IR. Some interesting results were obtained. The mesoporous zirconium organophosphonate with high surface area, large pore volume and pore size .The pore size can be easily controlled by adjustingthe amounts of anionic surfactant (SDS) in the initial reactants.The piperazrne of the mesoporous zirconium organophosphonate can be protoned under acidtive condition, whitch makes the materials with cation frameworks. So we have studied the mesoporous zirconium organophosphonates adsorption of acid dyestuff. And in the same condition, the adsorption process of the mesoporous zirconium organophosphonates adsorption of acid dyestuff is endothermic and higher adsorption efficiency.it can be seen that the Langmuir isotherm can accurately describe the adsorption behaviors of the synthesized materials. The design, synthesis of mesoporous zirconium organophosphonates with cation frameworks not only to make up for the mesoporous material framework for the neutral short-comings, but also have good acid dye adsorption performance, may be acid dyes in the field of wastewater treatment applications have a certain.
