Modified attapulgite, river bank ecological base material and preparation methods of modified attapulgite and river bank ecological base material
The invention discloses modified attapulgite, a river bank ecological base material and a preparation method thereof. The preparation method of the modified attapulgite comprises the following steps: taking charcoal and potassium hydroxide, adding water, stirring, performing suction filtration, drying and grinding a product, and sieving to obtain powder; mixing the powder with attapulgite powder, carrying out pyrolytic reaction in a protective gas atmosphere, and washing a product until the pH value is 6.5-7.0 after the reaction is ended, so as to obtain attapulgite-based biochar; the preparation method comprises the following steps: adding a ferric chloride solution and a thiourea solution into attapulgite-based biochar, stirring, drying, calcining the product in a protective gas atmosphere, mixing with water, adjusting the pH value of the system to 6.5-7.5, standing, and finally washing and drying. The modified attapulgite prepared by the invention has a unique layered chain structure and rod-like crystals, can play roles of adsorption, complexation and ion exchange on pollutants in the environment, and has relatively strong capability of adsorbing and immobilizing nitrogen and phosphorus in soil.
本发明公开了一种改性凹凸棒石、河岸生态基材及其制备方法。所述改性凹凸棒石的制备方法包括如下步骤：取生物炭和氢氧化钾，加水搅拌后抽滤，产物经烘干、研磨后过筛，得到粉末；将粉末与凹凸棒石粉末混合，在保护气体氛围下进行热解反应，反应结束后洗涤产物至pH=6.5~7.0，得到凹凸棒基生物炭；在凹凸棒基生物炭中加入氯化铁溶液和硫脲溶液，然后搅拌后烘干，将产物在保护气体氛围中煅烧，然后与水混合，调节体系pH为6.5~7.5并静置，最后洗涤后干燥即可。本申请制备的改性凹凸棒石具有独特的层链状结构和棒状晶体，对环境中的污染物能够起到吸附、络合和离子交换的作用，具有较强的吸附和固持土壤中氮、磷的能力。
