摘要: 碳酸钙是一种稳定的无机化合物,在自然界中广泛存在。多孔碳酸钙作为无机材料,以其比表面积大、无毒、生物相容性好等优点而被广泛应用于化工、医药、冶金、食品等行业。但多孔碳酸钙的结构、性能与应用受其制备方法和工艺影响严重,不同方法制备得到的多孔碳酸钙呈现出千差万别的结构和晶型。本文主要介绍了多孔碳酸钙的常用制备方法,主要有模板法、乳状液膜法、共沉淀法、溶剂/水热法、凝胶结晶法、盐析法等,并简要阐述了各种方法的制备原理与优缺点,同时将一些较新领域应用所取得的成果进行了归纳。指出国内外研究多孔碳酸钙在制备方法和工艺方面存在产品结构与性能难精确控制、过程节能环保不到位、原料利用较局限等问题,建议开展多孔碳酸钙在废水废气方面的应用研究。

Abstract: The calcium carbonate is a stable inorganic compound that exists widely on the earth. Porous calcium carbonate as an inorganic material was commonly used in chemical, pharmaceutical, metallurgy, food and other industries due to its large specific surface area, non-toxic, good biocompatibility, and other advantages. However, the structure, properties and application of porous calcium carbonate were seriously affected by the different fabrication methods or processes that could lead to different structures and crystal forms for porous calcium carbonate. In this paper, some commonly used fabrication methods, such as template method, emulsion liquid membrane method, coprecipitation method, sol-/hydro-thermal method, gel crystallization method and salting method, were introduced. The principles, advantages and disadvantages of various fabrication methods were briefly analyzed. Meanwhile, many research achievements on the application of porous calcium carbonate in various areas were discussed. It is pointed out that the study of porous calcium carbonate at home and abroad was insufficient in certain aspects, such as the difficulty to control precisely its structure and properties, poor energy saving and environmental protection, and the limited utilization of initial materials. It is suggested to explore the application of porous calcium carbonate in waste water and waste gas.
