| titleOfInvention | Preparation method of grading magnesium and aluminum hydrotalcite capable of adsorbing Cr(VI) |
| abstract | The invention discloses a preparation method of grading magnesium and aluminum hydrotalcite capable of adsorbing Cr(VI) and recycling. The method comprises the steps of firstly, sequentially adding a certain amount of sodium polyacrylate, Pluronic block copolymer P123 or F127 and a urea precipitating agent into magnesium salt solution and aluminum salt solution, stirring and dissolving and transferring to a hydrothermal kettle for performing hydrothermal treatment, naturally cooling, filtering, washing, vacuum drying and roasting a hydrothermal product to obtain magnesium and aluminum hydrotalcite with excellent Cr(VI) property. The method has the advantages of low-cost active ingredients, simple preparation technology, mild conditions, diversified product shapes and the like, and the prepared grading magnesium and aluminum hydrotalcite has good adsorption property on the Cr(VI) in a water body, and can be regenerated and recycled. |
