SELECTION OF LOW-COST SORBENTS AS A POTENTIAL MATERIAL FOR A PERMEABLE REACTIVE BARRIER BASED ON A BATCH STUDY

Maintaining of good quality of groundwater is of great public interest worldwide. However, this source is highly vulnerable to different pollution sources such as industry, mining, irrigation, and so on. The pollution problems are more often observed in Karst areas where large amounts of fresh water can be contaminated in a short time. The application of an in situ technique for remediation of contaminated groundwater is highly recommended due to its simplicity of performance and economic benefit. Among in situ techniques, the permeable reactive barrier is the most attractive method as it allows for using different materials in the barrier for remediation of contaminated groundwater. Materials for PBR must demonstrate good contaminant binding properties, the ability of their retention, excellent hydraulic properties, satisfactory mechanical properties for safe performance, and ensure a smooth flow through the barrier without disturbing the natural flow. Nowadays the research is focused on investigation of different natural materials to protect the environment, due to their low cost and availability in nature in large quantities. The purpose of this work is to investigate the efficacy of various natural materials such as natural and iron-modified zeolite, apatite, concentrated apatite, kaolin and raw bentonite to remove heavy metals (lead and cadmium) from contaminated groundwater using the in situ PBR. The batch test involves sorption experiments followed by leaching experiments. In sorption experiments, the amounts of metal removal by different sorbents were evaluated for cadmium and lead from simulated wastewater with similar initial metal concentrations. The leaching experiment included evaluation of metal retained by the saturated sorbents in ultrapure water with adjusted pH values at 2.98 and 6.07. Additionally, pH values of solutions were recorded during both experiments. Based on obtained results, the sorbents that provide the optimal metal removal and their retaining from the contaminated groundwater were selected.
