Phosphorus is widely used in agriculture and industry. However, excessive phosphorus can cause eutrophication in aquatic environment. Therefore, the development of an simple, efficient and economical method for phosphate removal from wastewater is urgently needed. In this study, calcium aluminum layered double hydroxides (CaAl-LDHs) and six amino acid intercalated calcium aluminum layered double hydroxides (CaAl-amino acid-LDHs) was prepared by a facile method. In order to identify optimal amino acid, the adsorption performance of phosphate for...
