Composite adsorption material for removing permanganate acid radicals from water and preparation method of composite adsorption material

Abstract

The invention discloses a novel and high-efficiency composite adsorption material prepared by loading lotus root starch on mullite fibers, and relates to the field of water treatment. The invention also discloses a method for removing permanganate acid radicals from water by using the mullite fibers loaded with the lotus root starch. By the method, the permanganate acid radicals in the water can be adsorbed and removed by the mullite fibers loaded with the lotus root starch under the conditions of optional pH values. An adsorption method is adopted; and compared with the traditional adsorption material, the composite adsorption material is low in cost and suitable for treating high-concentration wastewater. Besides, the composite adsorption material has the characteristics of large specific surface area, high adsorption efficiency, readily available materials, high-temperature resistance, high recycling rate and the like. Therefore, good environmental and economic benefits can be achieved when the permanganate acid radicals in the wastewater are removed by the composite adsorption material.

Description

technical field [0001] The invention relates to a composite adsorption material for removing permanganate radicals in water and a preparation method thereof, in particular to a novel material prepared by loading mullite fibers with lotus root starch, and belongs to the field of water evolution treatment. Background technique [0002] Permanganate (MnO 4 - ) is the highest valence state in manganese series, has strong oxidizing properties, generally cannot exist in water, and will be reduced to Mn 2- , it can cause harm to the human body through different ways, such as invading the human body through the digestive tract, respiratory tract, skin, etc., causing nausea, vomiting and other adverse reactions. Concentrated solutions or finished products are corrosive to the skin. People with large oral doses will die of circulatory failure. In addition, it can also accumulate in plants and animals through bioaccumulation, causing long-term threats to the ecological environment. ...
