In order to explore the adsorption characteristics of phosphorus from molecules with different molecular structures and varying number of phosphate groups on metal-modified biochar, walnut shell biochar was modified with LaCl to prepare lanthanum-loaded biochar (BC-La). Adsorption of four polar components, namely phytic acid (IHP), adenosine-5'-disodium triphosphate (5-ATP), hydroxyethylidene diphosphonic acid (HEDP), and sodium pyrophosphate (PP), was studied. The adsorption properties and mechanism of phosphorus sorption by BC-La were analyzed by SEM-EDS and FTIR for the different structures.

- A field experiment with the hyperaccumulator Arabis alpina intercropped with Vicia faba aimed to study the impact of root exudates on the accumulation and distribution of cadmium (Cd) and lead (Pb) in the plants.
- Results revealed that while soluble sugar exudation from A. alpina decreased significantly, free amino acids and organic acids were exuded in greater amounts compared to monocropped plants, indicating altered root chemistry.
- Moreover, the intercropped A. alpina exhibited higher levels of accumulated Cd and Pb, with a notable increase in Pb binding to cell components, suggesting that root exudates may enhance the migration and accumulation of these heavy metals in the plants.
