Abstract

The invention discloses a production method of hydroxyl-ferric oxide composite polystyrene polybasic copolymerized cation exchange resin. The method comprises the following specific steps: preparing a water phase and an oil phase; preparing a composite resin microsphere and synthesizing ion exchange resin, wherein a resin microsphere framework is formed through cross linking of styrene, methyl methacrylate and vinyl trimethoxysilane. The composite polystyrene polybasic copolymerized cation exchange resin provided by the invention has good high-temperature resistance and chemical stability resistance and a wide applicable range, and also has high mechanical strength, good pore diameter uniformity and high ion exchange capacity; the hydroxyl-ferric oxide composite polystyrene polybasic copolymerized cation exchange resin particularly has a good adsorption performance on heavy metal pollutants and is suitable for treating heavy metal wastewater.

Description

technical field [0001] The invention relates to a production method of an ion exchange resin, in particular to a production method of an iron oxyhydroxide composite polystyrene multi-component copolymerized cation exchange resin. Background technique [0002] Ion exchange resin is an important class of adsorption and separation materials. It is a porous spongy solid polymer substance in structure. Each resin particle is composed of a cross-linked network skeleton with a three-dimensional three-dimensional structure, and many movable particles are connected to the skeleton. functional basis. It is insoluble in general acid-base solutions and organic solvents, and can be used in various fields such as water treatment, food, pharmaceutical, petrochemical and environmental protection, and is playing an increasingly important role in modern industry. [0003] At present, the most widely used ion exchange resin is polystyrene-based resin, which has the advantages of easy-to-obtai...
