Based on the characteristics and effective components of steel slag desulfurization gypsum, a new type permeable reactive material was prepared by combining simulation experiment arsenic- antimony-contaminated groundwater remediation carried out. A combination X-ray fluorescent, BGRIMM Process Mineralogy Analyzing System (BPMA), ICP-MS, SEM-EDS detection analysis methods used to investigate effects particle size, gypsum ratio, slag-desulfurization mixed test block size performance wall remove arsenic antimony. The results show that composed (−4.75 + 1.18 mm) (−13.2 9.5 in 4:1 ratio achieved removal rates 91.85% for As 90.58% Sb, reducing their concentrations below drinking water standard. purpose using intercept heavy metals toxic ions surface runoff achieved. Arsenic adsorbed, physically encapsulated, lattice solidified C-S-H gel. This research provides cost-effective environmentally friendly solution storage while addressing metal pollution groundwater.
