Lead and Arsenic X-ray absorption spectral models fit as linear combination of known standards
In this study, smelter contaminated soil was treated with various soil amendments (ferric sulphate [Fe2(SO4)3], triple superphosphate [TSP] and biochar) to determine their efficacy in immobilizing soil lead (Pb) and arsenic (As). 
XAS were collected on soils and mine waste materials at the Materials Research …
