Abstract Phosphorus is an essential and limited resource. Incinerated sewage sludge ash (ISSA), which is phosphorus-enriched, shows a valuable potential for phosphorus recovery. Wet chemical method can effectively leach phosphorus from ISSA, but the major metals and heavy metals are leached at the same time, which influence the subsequent phosphorus recovery. In this study, Mg-Fe layered double hydroxides (LDH) is used to selectively adsorb and desorb phosphate. The phosphorus adsorption effects of uncalcined (LDHu) and calcined LDH (LDHc) as well as the mechanism of phosphorus adsorption and desorption were investigated. At high phosphorus concentrations (>1000mg/L), the phosphorus adsorption capacity of the LDHu was higher than that of the LDHc. The LDHu has a typical double layered structure. Phosphorus adsorption and desorption was achieved mainly by the phosphate precipitation-dissolution, electrostatic adsorption-repulsion, ligand interaction and ion exchange. After calcination, LDHc lost the layered structure, and was transformed into double metal oxide. There was no significant anion exchange process for the calcined LDH during adsorption and desorption. After LDHu or LDHc adsorption and alkaline desorption, the ISSA leachate could achieve good phosphorus purification effects, with the relative phosphorus purity increased from 36% to 77% and 69%, as well as a phosphorus recovery of 84% and 57%, respectively. The purified ISSA leachate is suitable for the subsequent valorization of high-value phosphorus-containing product.
