Cadmium

Cadmium is a chemical element; it has symbol Cd and atomic number 48. This soft, silvery-white metal is chemically similar to the two other stable metals in group 12, zinc and mercury. Like zinc, it demonstrates oxidation state +2 in most of its compounds, and like mercury, it has a lower melting point than the transit…Read moreCadmium removal mechanisms from aqueous solution by using recycled lignocelluloses Birol Kayranli Add to Mendeley https://doi/10.1016/j.aej.2021.06.036 Get rights and content Under a Creative Commons license open access Abstract ) of 51.28 mg g Keywords Cadmium Recycled lignocelluloses Adsorption mechanisms Thermodynamic Nomenclature K FCadmium removal mechanisms from aqueous solution by ... - ScienceDirectVolume 308, 1 September 2022, 119585 Micro-dynamic process of cadmium removal by microbial induced carbonate precipitation☆ Mingping Sheng a , Dinghua Peng a , Shihua Luo a , Ting Ni c , Huanyan Luo a , Renfeng Zhang a , Yu Wen a , Heng Xu a b Add to Mendeley https://doi/10.1016/j.envpol.2022.119585 Get rights and content Abstract KeywordsMicro-dynamic process of cadmium removal by microbial induced carbonate ...احصل على السعر
