Özet
The limited availability of water resources and the increasing population require careful use and protection of water. Heavy metals in waters bring serious risks to living things and the ecosystem. Couch grass is a noxious weed that grows together with agricultural products and often damages agricultural products, reducing yield and product quality. Therefore, it is characterised as a 'waste by-product'. In this study, it is aimed to design a system that has very low application process and raw material costs in removing heavy metals, one of the water pollutants, from the aqueous environment. In this context, exploring the literature it can be seen that although there are studies on the search for economical raw materials, adsorption mechanisms are used that cause energy consumption during the use of these raw materials in heavy metal removal. Couch grass collected from an agricultural area in Kocaeli province was being used in this research. In first phase, couch grass was washed, and dried in oven afterwards it was ground and sieved. Under optimal conditions, it was able to adsorb 100% of lead ions and 87% of cobalt ions. These results were also confirmed with SEM and EDX spectra. The striking aspect of the study is that couch grass is used for the first time as a green material in the removal of lead and cobalt heavy metals.
