Bacterially induced synthesis of low-Cd struvite coupled with Cd2+ biosorption under high cadmium stress [PDF]
RSC AdvancesChemical precipitation of struvite is promising for phosphorus recovery from wastewater. However, metal cations with high phosphate affinity, such as Cd2+, can reduce struvite phase purity and promote heavy-metal incorporation, limiting practical safety.
