硼吸附材料研究进展

硼化物因具有质轻、阻燃、耐热、高硬、耐磨等优良性能而应用广泛,目前国内硼资源开发力度不足导致硼进口量高达70%。随国内盐湖与海水资源开发产业兴起,利用提硼彻底、工艺简洁、材料可循环利用的吸附法从水溶液中分离提取硼资源成为研究热点。综述了国内外多种无机硼吸附材料、有机硼吸附材料、有机-无机杂化硼吸附材料的研究现状,重点对比了有机硼吸附材料中的螯合树脂型和螯合膜型材料,并对硼吸附材料的发展趋势进行了展望,为盐湖卤水提硼及海水淡化提硼产业技术开发中硼吸附材料的选择提供参考。

Research Progress of Adsorbent Materials for Boron Removal

Boride is widely used due to its light weight, flame retardant, heat resistance, high hardness and wear resistance.However, the current shortage of domestic boron products led to imports as high as 70%.With the development of salt lake and seawater industry in China, the extraction technology of boron resources of aqueous solution has gradually become a research hotspot.The research status and development trend of inorganic boron adsorption materials, organic boron adsorbent materials and organic-inorganic hybrid boron adsorption materials are reviewed in this paper.The organic chelating resin and chelating membrane boron adsorption materials were specially compared in detail.It should be a reference for the application selection of the boron adsorbing material in the technical development of the salt lake and seawater boron resource industry.
