Abstract

Abstract:

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 SiO₂ and 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.

Key words: Saline-alkali land improvement, Petroleum contaminated soil remediation, Water eutrophication treatment, Solid waste composting, Environmental remediation agents
