| dc.description.abstract | The development of the industry has resulted in a proportional increase in waste materials. Waste industrial products play a major role in the pollution of nature along with seas, lakes, and various water resources around the world. Organic dyes, which do not degrade in nature and have carcinogenic effects, are important industrial wastes. The improvement of wastewater is a research topic that has gained importance in recent years. In this study, the biosorption of Congo red dye from aqueous solution with dried mint leaves was investigated. The experiments were carried out at 20 °C and the natural pH of the dye. The process was optimized by examining the parameters of initial dye concentration, amount of biosorbent and contact time. It was determined that the biosorption equilibrium conformed to the Langmuir isotherm (R2=0.9815) and the maximum biosorption capacity (qmax) was 60.24 mg/g. In addition, the process conforms to the pseudo-second-order (R2=0.9946) kinetic model. As a result of the process, the removal of the Congo red dye from the dried mint leaves from the aqueous solution was achieved at a level of approximately 70%. | |
