| description | The invention discloses a preparation method for modified sepiolite and an application of the sepiolite in environmental restoration. The preparation method for the modified sepiolite comprises the following steps of (1) enabling natural sepiolite and deionized water to be mixed at a mass ratio of 1 to (10-50), stirring to form a sepiolite turbid liquid, and standing for 6-24h; (2) adding sodium diethyldithiocarbamate into the solution obtained in the step (1) and stirring, wherein the mass ratio of sodium diethyldithiocarbamate to sepiolite is (0.05-0.3) to 1; and (3) performing solid-liquid separation on the stirred solution, washing the solid body by deionized water, and drying and grinding to obtain the modified sepiolite.
本发明公开了种改性海泡石的制备方法及其在环境修复中的应用，改性海泡石的制备方法包括以下步骤：（1）按质量比，将天然的海泡石:去离子水=1:10-50混合，搅拌形成海泡石悬浊液后静置6-24h；（2）将二乙基二硫代氨基甲酸钠投加到步骤（1）的溶液中，搅拌；其中二乙基二硫代氨基甲酸钠与海泡石的质量比=0.05-0.3:1；（3）将搅拌后的溶液固液分离，固体用去离子洗涤、干燥、研磨后即得到改性海泡石。 |
