Geological polymer (zinc slag/Metakaolin geopolymer, ZMG) was synthesized by using zinc slag and metakaolin as raw materials and phosphoric acid as activating agent. The effects of the ratio of raw materials on the mechanical properties, formation of mineral phases, microstructure and pore size distribution of geopolymers were studied. The geopolymer was employed as Fenton-like catalyst for degradation of direct copper salt blue 2R simulated dye wastewater. The effects of the ratio of raw materials, catalyst dosage, pH value and H2O2 concentration on dye degradation rate were systematically investigated. The results showed that the 7-day compressive strength of ZMG-50 geological polymer with a zinc slag proportion of 50% (in mass fraction) could reach 19.9 MPa. Zinc slag can eliminate mechanical pores, improve mesoporous structure and increase specific surface area of geopolymer. The catalytic results showed that ZMG-50 had the best catalytic performance under the conditions of catalyst dosage of 8 g/L, pH value of 2.5 and H2O2 concentration of 0.32 mmol/L, the degradation rate of direct copper salt blue 2R dye could reach 96.2% after 42 min reaction, and it had good stability and reuse performance.

以锌渣和偏高岭土为原料,磷酸为激发剂制备地质聚合物(ZMG)。研究原料配比对地质聚合物力学性能、物相组成、微观结构和孔径分布的影响。将所制地质聚合物应用于Fenton-like催化降解直接铜盐蓝2R模拟染料废水,系统考察了原料配比、催化剂用量、pH值、H2O2浓度对染料降解率的影响。结果表明:锌渣占比为50%(质量分数)地质聚合物样品(ZMG-50)的7 d抗压强度可达19.9 MPa;锌渣可消除地质聚合物的机械孔、改善介孔结构、提高比表面积。催化结果表明,在催化剂用量为8 g/L、pH值为2.5、H2O2浓度为0.32 mmol/L的条件下,样品ZMG-50的催化性能最佳,经42 min反应后直接铜盐蓝2R染料的降解率可达96.2%,且具有良好的稳定性和重复使用性能。

以锌渣和偏高岭土为原料,磷酸为激发剂制备地质聚合物(ZMG)。研究原料配比对地质聚合物力学性能、物相组成、微观结构和孔径分布的影响。将所制地质聚合物应用于Fenton-like催化降解直接铜盐蓝2R模拟染料废水,系统考察了原料配比、催化剂用量、pH值、H2O2浓度对染料降解率的影响。结果表明:锌渣占比为50%(质量分数)地质聚合物样品(ZMG-50)的7 d抗压强度可达19.9 MPa;锌渣可消除地质聚合物的机械孔、改善介孔结构、提高比表面积。催化结果表明,在催化剂用量为8 g/L、pH值为2.5、H2O2浓度为0.32 mmol/L的条件下,样品ZMG-50的催化性能最佳,经42 min反应后直接铜盐蓝2R染料的降解率可达96.2%,且具有良好的稳定性和重复使用性能。

Geological polymer (zinc slag/Metakaolin geopolymer, ZMG) was synthesized by using zinc slag and metakaolin as raw materials and phosphoric acid as activating agent. The effects of the ratio of raw materials on the mechanical properties, formation of mineral phases, microstructure and pore size distribution of geopolymers were studied. The geopolymer was employed as Fenton-like catalyst for degradation of direct copper salt blue 2R simulated dye wastewater. The effects of the ratio of raw materials, catalyst dosage, pH value and H2O2 concentration on dye degradation rate were systematically investigated. The results showed that the 7-day compressive strength of ZMG-50 geological polymer with a zinc slag proportion of 50% (in mass fraction) could reach 19.9 MPa. Zinc slag can eliminate mechanical pores, improve mesoporous structure and increase specific surface area of geopolymer. The catalytic results showed that ZMG-50 had the best catalytic performance under the conditions of catalyst dosage of 8 g/L, pH value of 2.5 and H2O2 concentration of 0.32 mmol/L, the degradation rate of direct copper salt blue 2R dye could reach 96.2% after 42 min reaction, and it had good stability and reuse performance.
