Soil water content affects metalloid immobilisation by Fe and biochar sorbents

The results of a comprehensive laboratory study performed by our PhD student Szimona Zarzsevszkij were published in the journal Soil Use and Management (IF = 3.8)! The research summarizes the effects of different soil water contents on the immobilization efficiency of several iron and biochar-based sorbents in a contaminated mine soil towards the risk elements antimony (Sb) and arsenic (As). After soil incubation with the sorbents, scanning electron microscopy analysis revealed solid-phase changes of the sorbents and that sorption onto secondary Fe minerals was the dominant Sb/As immobilizing mechanism. Such imitation studies are crucial for evaluating risk element affinity towards novel sorbents prior to their full-scale field application.
