Description
technical field [0001] The invention relates to a green and environment-friendly adsorption material for waste water containing cadmium compounds. Background technique [0002] In many industrial processes, such as electroplating, tanning, mining, steelmaking, and dyeing, a large amount of wastewater containing cadmium heavy metal ions will be generated, and the release into the environment will endanger human health and the ecological environment. Therefore, the treatment of cadmium-containing heavy metal ion wastewater has always been the focus and difficulty of people's attention and research. In recent years, the development of innovative technologies to reduce the content of cadmium heavy metal ions in aqueous solutions to a safe range has attracted widespread attention and attention. At present, domestic and foreign treatment methods generally include activated carbon adsorption method, biodegradation method, modified bentonite adsorption method and photocatalyst degr...
