Abstract :
Abstract Metals in the environment raise questions about food safety and, by extension, about human existence. Rocks, ores, volcanoes, and the weather-induced metal leaching the natural sources of heavy metals in ecosystems are the products of processes that result in soil. When the quantity of heavy metals in some ecosystems rises dramatically as a result of human activity, it becomes a serious problem. This work aims to utilise Mentha piperita and other affordable materials to extract heavy metal ions from wastewater. A new, eco-friendly technique called biosorption has recently come to light. The presence of heavy metals in a country's water supply is one of the most pressing environmental concerns. Heavy metal poisoning of water supplies has been rampant, endangering aquatic and terrestrial species alike. We investigated the extent to which Mentha piperita was able to adsorb several metal ions, including Lead (Pb+2ions), Cadmium (Cd+2ions), Zinc (Zn+2ions) and Nickel (Ni+2ions). The removal percentage of Cadmium Cd+2, Lead Pb+2, Zinc Zn+2, Nickel Ni+2 were 44%, 28%, 39% and 20% respectively. While recorded (40%, 26%) for Cd+2 and Pb+2, (38%, 38%) for Cd+2 and Zn+2, (34%, 18%) for Cd+2and Ni+2, (24%, 36%) for Pb+2 and Zn+2, (21%, 17%) for Pb+2 and Ni+2, (33%, 16%) for Zn+2 and Ni+2, (31%, 19%, 29%) for Cd+2, Pb+2, Zn+2 , (29%, 15%, 14%) for Cd+2, Pb+2, Ni+2, (26%, 27%, 13%) for Cd+2, Zn+2, Ni+2, (14%, 24%, 12%) for Pb+2ions, Zn+2ions, Ni+2ions (22%, 12%, 19%, 10%) for Cd+2 ions, Pb+2ions, Zn+2ions , Ni+2ions respectively. The expensive cost of activated adsorbents limits their widespread application. Therefore, we need to find long-term solutions that address the root cause of the problem.
