Environment materials (humic acid (HA), super absorbent polymers (SAP), fly ash (FM) and zeolite (FS)) were used as amendments to immobilize heavy metal Pb and Cd in artificial contaminated soils. The results showed that soil pH and EC changed after the application of single or combined and co-application amendments. The leaching Pb in the single-Pb contaminated soils amended with HA, FM, C1 (HA, SAP, FM, FS) and C2 (HA, SAP, FM) were 93%, 87%, 59% and 77% of the control without amendments, respectively. The leaching Cd in the single-Cd contaminated soils amended with SAP and C3 (HA, SAP, FS) were 64%, and 83% of the control, respectively, in four-steps leaching. The leaching Pb in the Pb-Cd co-contaminated soil amended with HA, C2 and C3 were 41%, 95% and 77% of the control, respectively. The leaching Cd in the Pb-Cd co-contaminated soil amended with HA, SAP and C3 were 85%, 72% and 55% of the control, respectively. The results indicated that C1 and SAP was the best amendments for single Pb and Cd contaminated soil, respectively. While the combined amendment, HA and C3 could prevent Pb and Cd to be leached from co-contaminated soils, respectively.

In this study, the geochemical properties of heavy metal-contaminated soils from a Korean military shooting range were analyzed. The chemical behavior of heavy metals was determined by analyzing the soil pH, heavy metal concentration, mineral composition, and Pb isotopes. In total, 24 soil samples were collected from a Korean military shooting range. The soil samples consist of quartz, albite, microcline, muscovite/illite, kaolinite, chlorite, and calcite. Lead minerals, such as hydrocerussite and anglesite, which are indicative of a transformation into secondary mineral phases, were not observed. All soils were strongly contaminated with Pb with minor concentrations of Cu, Ni, Cd, and Zn. Arsenic was rarely detected. The obtained results are indicated that the soils from the shooting range are contaminated with heavy metals and have evidences of different degree of anthropogenic Pb sources. This study is crucial for the evaluation of heavy metal-contaminated soils in shooting ranges and their environmental effect as well as for the establishment of management strategies for the mitigation of environmental risks.

The Cost

Coal fly ash was used to synthesize X-type zeolite by alkali fusion followed by hydrothermal treatment. Characteristics of the various Fly ash samples were carried out. Coal proximate analysis was done. Batch experiment was carried out for the adsorption of some heavy metal ions on to synthesized Zeolite. The cost of synthesized zeolite was estimated to be almost one-fifth of that of commercial 13X zeolite available in the market.
