In this research, the adsorption behavior of zeolites with respect to iron (Fe), zinc (Zn), and copper (Cu) has been studied in order to assess its application to heavy metal removal in polluted settings caused by acid mine drainage (AMD). The St. Cloud zeolitic deposit used in this project was characterized using a sieve analysis; the effective diameter and coefficient of uniformity were calculated. Batch studies were performed, and the samples were analyzed using ICP-OES. Batch studies used metal concentrations ranging from 50 mg/L to 650 mg/L. Freundlich, Linear, Langmuir, and BET adsorption isotherms were applied and evaluated to the …

Using Zeolite For Soil Moisture Retention And Salinity Control, Mark Torres
Open Access Theses & Dissertations
There is a great need in the desert southwest United States for exploring ways to save water in agriculture as it accounts for up to 90 percent of water consumption in many western states (USDA 2016). As surface water reaches critical lows the dependence on ground water has increased leading to the need for deeper wells with higher salt concentrations. The studies conducted for this research included using zeolites from the St Cloud Mining Company in Winston, New Mexico to determine the feasibility of using these zeolites to help and retain moisture in zeolite treated soils. The Volumetric Water Content …
