Preparation And Properties Of Ammonium Phosphomolybdate Composite

Based on the characteristics of ammonium phosphomolybdate,chitosan,loofah and other materials,the granular ammonium phosphomolybdate was prepared by chemical precipitation method;the granular ammonium phosphomolybdate / chitosan complex was prepared by sol-gel method and the granular ammonium phosphomolybdate / loofah fiber composites were prepared by In-situ Synthesis.The preparedsamples were characterizedby XRD,IR,SEM and other methods.The prepared granular ammonium molybdophosphate and granular ammonium molybdophosphate / chitosan composites were applied for adsorption of cesium ions,meanwhile,the Adsorption Kinetics and thermodynamics model were studied.The influence of temperature,time and pH on the adsorption effect was discussed for the optimal adsorption conditions.The adsorptive capacity and recycling rate of cesium of granular ammonium molybdophosphate / loofah fiber composite materials were studied,providing the basis for studying new adsorption material with excellent adsorption performance and easy recovery.
