Water Pollution resulted from environmental pollutants such as organic compounds and heavy metal ions is a serious problem due to the severe toxicity and carcinogenic nature of these compounds. Among the various methods of water purification, the adsorption mechanism with the low cost, abundance, and availability of the natural adsorbents is considered as one of the best practices. Among many natural materials, such as: coconut peel, orange peel, rice peel, corn straw, and cane bagasse, wastes resulted from oil products, fly ash, cellulose and lignocellulose compounds and rubber wastes are used in the adsorption process. In this article, the impact and efficiency of some of these waste materials in the cleaning and purification of the water systems will be discussed.
