摘要： A method for producing a surface-activated crystalline titanium oxide product having a high adsorptive capacity and a high rate of adsorption with respect to dissolved contaminants includes the steps of preparing a titanium oxide precipitate from a mixture comprising a hydrolysable titanium compound and heating the precipitate at a temperature of less than 300° C., without calcining the precipitate. Preferably, the titanium oxide product includes crystalline anatase having primary crystallite diameters in the range of 1-30 nm. The surface-activated crystalline titanium oxide product is used in methods to remove dissolved inorganic contaminants from dilute aqueous streams by suspending the product in an aqueous stream or by filtering an aqueous stream through a bed of the product. In another method, a hydrolysable titanium compound is added to an aqueous stream so that titanium oxides form as a co-precipitate with dissolved contaminants within a bed of particulate material.
摘要翻译：制备具有高吸附能力和高溶解污染物吸附率的表面活化结晶二氧化钛产品的方法包括以下步骤：从包含可水解的钛化合物的混合物中制备氧化钛沉淀物并加热沉淀物温度低于300℃，不煅烧沉淀物。优选地，氧化钛产品包括具有1-30nm范围内的初级微晶直径的结晶锐钛矿。表面活化的结晶二氧化钛产品用于通过将产物悬浮在含水物流中或通过将产物的床过滤到水中而从稀的水流中除去溶解的无机污染物的方法中。在另一种方法中，将水解性钛化合物加入到水流中，使得钛氧化物与颗粒材料床内的溶解污染物形成共沉淀物。
