Phosphorus-modified biochar from salvia miltiorrhiza dregs: synthesis, characterization, and dual-functional synergy for heavy metal immobilization and soil fertility augmentation

Abstract Phosphorus-modified biochar (3K-BC) was prepared from Salvia miltiorrhiza dregs via phosphate modification and applied for lead (Pb) and cadmium (Cd) removal from aqueous solutions and soil. The successful incorporation of orthophosphate into the biochar was confirmed by 31P NMR and other a...
