Boron adsorption resin containing difunctional groups

Abstract

The invention discloses boron adsorption resin containing difunctional groups and a preparation method thereof. The boron adsorption resin containing the difunctional groups is characterized in that the boron adsorption resin containing the difunctional groups is prepared by the reaction of halogenated acylation resin and amino sugar. The carrying quantity of the difunctional groups of the boron adsorption resin prepared by the method is 0.1 to 2.8mmol / g, and the preparation process of the resin is safe and simple. The difunctional groups of alpha-glycyl and orthohydroxy group in the resin generate a synergistic action, the functions of adsorption and chelation of the resin to boron are enhanced, and the resin can replace the traditional boron-specific resin.

Description

technical field

[0001] The invention belongs to the field of functional polymers. It specifically relates to a boron-absorbing resin containing two functional groups. Background technique

[0002] As an important industrial raw material, boron is widely used in many fields such as metallurgy, nuclear technology, military industry, aerospace, energy, agriculture, medicine and automobiles. The discharge of a large amount of sewage in the production process of boron compounds not only leads to the loss of a large amount of boron resources, but also causes serious pollution to the environment. The boron-containing wastewater that is lost and pollutes the environment is not discharged up to the standard, which makes the boron content in people's drinking water sources too high, thus causing many diseases. The World Health Organization (WHO) requires that the concentration of boron in drinking water be less than 0.3 mg / L. Therefore, the study on the treatment and reuse of boron ...
