Abstract

The invention discloses epoxy acrylate extraction resin preparation and application of epoxy acrylate extraction resin in germanium extraction. The epoxy acrylate extraction resin preparation comprises the following steps: adding epoxy resin, a catalyst and a polymerization inhibitor in a device, uniformly stirring, after slowly dropwise adding acrylic acid within 1-2 hours, performing a heating reaction, after the acid value is measured to be smaller than 10, stopping the reaction, cooling, adding a diluent and a cross-linking agent, and performing a stirring reaction, thereby obtaining epoxyacrylate resin; and adding deionized water and a surfactant in the device, slowly dropwise adding a mixed solution prepared from epoxy acrylate resin, an extraction agent and an initiator through a constant pressure dropping funnel after the stirring reaction, performing suspension polymerization for 30-40 minutes, heating and performing a stirring reaction again, washing, and drying, thereby obtaining the epoxy acrylate extraction resin. The extraction resin solves the problem of massive loss of the extraction agent in an extraction resin prepared according to a physical impregnation methodin germanium extraction and separation, the preparation method is simple, and the extraction resin is low in cost, is convenient to recover, can be recycled, is low in environmental pollution, and cangenerate huge economic and social benefits.

Description

Technical field[0001]The invention relates to an epoxy acrylic acid extraction resin capable of efficiently extracting and separating germanium and a preparation method thereof.Background technique[0002]The extraction resin is prepared by adsorbing the extractant onto a conventional macroporous polymer carrier (polar or non-polar carrier), and is used for the extraction and extraction of various metals. It has both particles and liquids in the extraction and elution. The characteristics of both. Its most significant feature is its large pore structure. Unlike other types of resins used in separation, chelating resins have higher selectivity, but their application in separation is subject to the complexity of synthesis, high cost and functional groups. The difficulty and time-consuming bonding to resin are limited. Therefore, it is of great significance to design and develop a synthetic method that is simple and can efficiently extract and separate metal ions.Summary of the invention...
