Study on the Preparation of a Polydiethylene Phenyl Phosphate Resin and its Adsorption of Cu2+ in Wastewater

Abstract

In view of the problems and imperfections in the synthesis of phosphoric acid resins by existing techniques, we prepared a different phosphoric acid resin and used it to adsorb Cu2+ in wastewater. When phosphoric acid resin is prepared using cross-linked polydiethylbenzene resin as a matrix, the experimental raw material can be more selective and the experimental process is safe and non-toxic. The particle size of the synthesized resin is uniform, most of which are distributed in 100-300 μm, and the functional group content can be as high as 2.4 mmol/g. The static/dynamic adsorption on Cu2+ is excellent, with a static adsorption capacity of 51.2 mg/g. When hydrochloric acid is used as an eluant, the resin has favorable reproducibility, which provides a reference value for the preparation and application of phosphate resins.
