Preparation method of hexavalent chromium reducing agent for nano-loaded cement
The invention discloses a preparation method of a hexavalent chromium reducing agent for nano-loaded cement, and belongs to the technical field of preparation of building materials. The method comprises the following specific steps: sequentially adding a certain amount of an antimony compound, organic alkali and a carrier into a glass flask, stirring for a certain time at a certain temperature, and performing standing; and carrying out suction filtration on the obtained precipitate, respectively washing with deionized water and absolute ethyl alcohol, and drying at a certain temperature to obtain the hexavalent chromium reducing agent for the nano-loaded cement. The hexavalent chromium reducing agent prepared by the invention has the advantages of low doping amount, high reduction efficiency, no negative influence on cement-related properties and the like, and the method is simple and easy to operate and has industrial popularization value.
本发明公开了一种纳米负载型水泥用六价铬还原剂的制备方法，属于建筑材料制备技术领域。该方法的具体步骤为：将一定量的锑化合物、有机碱和载体依次加入玻璃烧瓶中，在一定温度下搅拌一定时间后静置。将所得沉淀进行抽滤，用去离子水和无水乙醇分别洗涤后，在一定温度下干燥，即得到一种纳米负载型水泥用六价铬还原剂。本发明所制备的六价铬还原剂具有掺量低、还原效率高，对水泥相关性能没有负面影响等优点，且该方法简单，易操作，具有工业推广价值。
