Curing agent for copper ion polluted kaolin and sample preparation method
The invention discloses a curing agent for copper ion polluted kaolin and sample preparation method, wherein the curing agent comprises red mud, fly ash, quicklime, cement and water, and the mass ratio of red mud to fly ash in all raw materials is 1:1, 3:7, 7:3, 2:8, 8:2, 4:6 and 6:4. The doping amount of calcium oxide is 10% of the total mass of the red mud and the fly ash. The cement mixing amount is 7%, and the water content is 45%. The highest compressive strength of the curing agent for the copper ion polluted kaolin prepared at normal temperature can reach 8.13 Mpa or above within 28 d,the ion leaching concentration is only 0.014 mg/l, and the problem that the copper ion polluted kaolin harms the environment is solved; in addition, the red mud fly ash is adopted as the raw material,so that the preparation process of the curing agent is simple, industrial production is easy to achieve, and the curing agent is suitable for industrial production. According to the invention, the harm of red mud and fly ash to the environment and the resource utilization of red mud and fly ash are actively promoted.
本发明公开了一种铜离子污染高岭土的固化剂及试样制备方法，其中固化剂包括赤泥、粉煤灰、生石灰、水泥和水，且所有原料中赤泥和粉煤灰质量之比为1:1、3:7、7:3、2:8、8:2、4:6、6:4。氧化钙掺量为赤泥和粉煤灰总质量的10%。水泥掺量为7%，含水量为45%。在常温下制备的铜离子污染高岭土的固化剂的抗压强度在28d最高可以达到8.13Mpa以上，离子浸出浓度仅仅为0.014mg·L‑1，解决了铜离子污染高岭土对环境的危害问题，本发明采用赤泥粉煤灰为原料，制备固化剂制备工艺简单，易于实现工业化生产，本发明降低赤泥、粉煤灰对环境的危害以及二者的资源化利用起到积极的推动作用。
