Description

technical field [0001] The invention belongs to the fields of composite materials, coordination chemistry and environmental pollution prevention and control, and in particular relates to a coordination polymer reinforced basalt fiber composite material and a preparation method thereof. Background technique [0002] In recent years, the content of heavy metals in rivers and lakes has been increasing year by year. At the same time, they are accumulated in vegetables, meat, fish, seafood, and enriched in animals and plants. They have seriously threatened people's health. Water heavy metal pollution has become a global environmental problem. . At present, due to the mining, smelting, and processing of heavy metals in China, many heavy metals such as lead, mercury, cadmium, chromium, and copper enter the atmosphere, water, and soil, causing serious environmental pollution. At the same time, coal chemical industry, petroleum and natural gas exploration, chemical catalysis and oth...
