Adsorption removal of dyes by nanoparticles

Today, synthetic dyes are vastly used in many industries. These dyes are produced from organic materials in laboratories and due to their nature, they are considered as toxic, carcinogenic and non-degradable substances. The presence of these substances either indoors or outdoors. has caused irreparable effects the nature, and this has made it necessary to eliminate these pollutants. One of the promising methods to remove theses pollutants is the physical/chemical adsorption, which is used in the industry due to its ease, low cost, and high efficiency. Adsorbent selection is one of the most important factors in the adsorption process. Some adsorbents have a direct effect on the cations and anions of the dye. In this paper, an attempt has been made to get to know a number of nanoparticles that help us remove dyes through the adsorption technology.
