Abstract
In recent years, with the rapid development of our national economy, the current industrial development is very fast, the scale is increasing, the discharge of industrial wastewater is increasing, and the pollution of water resources in our country is also serious. Because many kinds of dye wastewater contain many non-degradable organic substances, their presence in water not only affects the propagation of light, This makes it impossible for multiple ecosystems and microbial systems in the water to quickly complete photosynthesis and maintain metabolism; Heavy metal waste water can go through the food chain and cause irreversible poisoning in humans, and adsorption methods are used to remove some of the toxic effects that cannot be achieved. Degradation of pollutants in the process of removal has a very important role. The aim of this study was to prepare neutral starch microspheres from natural soluble starch and to prepare a new kind of green and degradable anion starch microspheres by anion reaction. It was used as adsorbent to treat methylene blue positive dyestuff wastewater and heavy metal ion wastewater represented by copper and lead. The adsorption properties and adsorption mechanism of methylene blue and Cu2+, Pb2+ were analyzed from the point of view of thermodynamics and kinetics. The results provide some theoretical basis and application basis for wastewater treatment.
