一种新型环境修复材料的制备及其功能分析

以韩国特有的五色长石黏土矿物为原料，经特殊方式加工后制成一种新型环境修复制剂（简称QE粉末）。为了探索该新型材料的基本理化性质及其在环境修复领域的应用潜质，分别研究了QE粉末对铁钉氧化及水体pH值和非接触条件下对水体理化性质的影响，以及QE粉末自身表面放热的情况。结果表明：与常规的SiO₂粉末及空白对照相比，QE粉末能降低铁钉在盐水中的氧化程度；其抗氧化性通过铁钉在盐水中氧化形成的沉淀物（Fe₂O₃）表征，QE粉末形成的棕红色絮状物最少，说明其抗氧化性最好。此外，QE粉末能调节水体pH值，并稳定在7.5左右。在非接触条件下，QE粉末可平衡水体pH值，提高水体温度，降低水体氧化还原电位；其对水体的密度、表面张力等理化性质也均有一定影响。对QE粉末表面的热分布场的测试结果表明，QE粉末的放热比SiO₂粉末增加0.1～0.6℃。最后，对QE粉末在盐碱土壤改良、石油土壤修复、水体富营养化和堆肥资源化等方面的潜在应用价值进行探讨。

Preparation and Function of a New Environmental Restoration Material

A new environmental restoration material, namely Quantum Energy (QE) powder, was produced from five-colored typical feldspar family of clay minerals(Osaekhyulto) in South Korea by special processing technology. To explore the function of the QE powder and its potential application in the field of environmental remediation, a set of laboratory experiments were conducted. The effects of QE powder on the degree of oxidation of iron nail in salt solution and the pH value of water were examined; moreover, the influence of QE powder on the physical and chemical properties of water in non-contact manner, and its self-heating effects were also investigated. The results showed that QE powder could decrease the oxidation of iron nail in salt solution. The formation of ferric oxide precipitate in treatment with QE powder was less than that with SiO2and CK, indicating that QE powder would be a better antioxidant. Besides, QE powder could regulate the pH of water, which would stabilize at around 7.5. In non-contact manner, QE powder could balance the pH, increase the temperature, and decrease the oxidation-reduction potential of water. Meantime, it could also affect the water density and surface tension. Moreover, QE powder had a better self-heating capacity, and the temperature per unite surface area of QE powder was 0.1-0.6°C higher than that of SiO2. Therefore, QE powder, due to these unique and special characteristics, has great potential value on the environmental remediation, including saline-alkali land improvement, petroleum contaminated soil remediation, water eutrophication treatment and solid waste composting. Based on the status of environmental remediation at home and abroad, combined with the special functions of QE powder, prospects and recommendations of QE powder in environmental restoration were discussed.
