Coordination polymer reinforced basalt fiber composite material and preparation method thereof

Abstract

The invention discloses a coordination polymer based enhanced basalt fiber composite material for heavy metal adsorption, and a material preparation method thereof. A heavy metal adsorption material is prepared from 20 to 80 weight parts of pure natural basalt fiber, 1 to 20 weight parts of sulfydryl-containing silane coupling agents, 10 to 70 weight parts of amino polycarboxylic acid organic ligands and 10 to 70 weight parts of inorganic calcium salt; the material synthesis is performed in a mode of combining chemical coupling, high-speed stirring and hydrothermal method; then, after solid and liquid separation and purification washing, vacuum drying is performed; finally, a yellow solid material is obtained. The preparation method is simple; the operation is easy; specific process equipment is not needed; the energy consumption is low; various excellent performance such as high adsorption capacity, high adsorption performance, high anti-COD interference performance, corrosion resistance, high-temperature resistance, high intensity and good material regeneration performance is realized; the prepared heavy metal adsorption material has an ideal adsorption effect on mercury, lead, chromium, cadmium, copper and zinc; economic values and environment-friendly significance are realized; the industrialization is easy.

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...
