文摘

Aggregate chemistry has a minor role in heavy metal removal. Cement plays a vital role in long term removal. Permeable reactive concrete (PRC) is an effective permeable reactive material. Componential influences have never before been investigated for PRCs. Removal is driven by adsorption, precipitation, ion exchange and diffusion.
