| titleOfInvention | Preparation method of calcium-based magnesium hydroxide for adsorbing heavy metal copper |
| abstract | The invention discloses a preparation method of calcium-based magnesium hydroxide for adsorbing heavy metal copper, which mainly solves the problems of complex preparation process, dangerous preparation process and great environmental pollution in the prior art. Its implementation scheme is: adding the prepared calcium chloride aqueous solution and the surfactant sodium lauryl sulfate aqueous solution or the surfactant L-alanine aqueous solution to the prepared magnesium chloride aqueous solution and mixing; then add to the solution. The prepared sodium carbonate aqueous solution and sodium hydroxide aqueous solution are heated and stirred to obtain a calcium-based magnesium hydroxide suspension modified by a surfactant, and the suspension is sequentially aged, washed, filtered and dried to obtain calcium-based magnesium hydroxide. Magnesium hydroxide nanocrystals. The preparation process of the invention is simple, the risk in the preparation process is low, and the environmental pollution is small, and the method can be used in the main industries such as chemical industry, paint, dyestuff, and paper making, which are prone to copper pollution, and treat the copper in the discharged wastewater to prevent and control copper. Pollution. |
