Preparation method of geopolymer heavy metal ion adsorption material capable of being paved
The invention provides a preparation method of a geopolymer heavy metal ion adsorption material capable of being paved, and belongs to the field of heavy metal ion adsorption materials. The preparation method of the adsorption material comprises the following steps: adding water glass into a mixed solid waste raw material of slag and fly ash, adding carboxymethyl chitosan and a proper amount of water at the same time, ensuring that the total solid-to-liquid ratio is 1: 0.7, and rapidly stirring to prepare slurry; pouring the slurry into a mold, oscillating for 2-5 minutes, curing at room temperature, and demolding; and putting a molded part after demolding into a curing box, and curing for 8-14 days at 60-70 DEG C to obtain the block modified geopolymer heavy metal ion adsorption material capable of being paved. The block adsorbing material can be directly paved at the bottom of a road or a river runner to actively adsorb flowing heavy metal ions; on the other hand, solid waste utilization can be achieved, the production process is low in energy consumption and free of pollution, and the environment-friendly requirement is met.
本发明提供一种可铺装的地质聚合物重金属离子吸附材料的制备方法，属于重金属离子吸附材料领域。该吸附材料的制备方法步骤是：将水玻璃加入到矿渣和粉煤灰的混合固体废弃物原料中，同时加入羧甲基壳聚糖，加入适量水，保证总固液比为1:0.7，快速搅拌，制得浆体；然后将浆体倒入模具中，振荡2~5 min，室温下养护后脱模；脱模后的成型件放入养护箱中，在60~70℃下，养护8~14 d，得到可铺装的块体改性地质聚合物重金属离子吸附材料。该块体吸附材料，可直接铺装于道路或河流流道底部，对流经的重金属离子进行主动吸附；另一方面，可实现固废利用，生产过程低耗能、无污染，符合环保要求。
