A review on removal of industrial dyes using low cost natural adsorbents

Abstract

In the present world scenario, environmental problem is a very serious problem due to the industrialization and urbanization development results in air, water and soil pollutions. Water is the main consuming sources in the many of the industries and results in waste industrial effluents discharge into the environment. Their impacts are directly and indirectly affect our living organism and vegetation. The present review paper describes about the dyes effluents removal using low-cost natural adsorbents. Generally, dyes are Carcinogenic, Mutagenic and toxic to life. Adsorption technique is an effective method for the removal of dye. Recently, many of the scientists working on natural adsorbents, since the removal efficiency is significant in case of natural absorbents compared with synthetic adsorbents. Since, the synthetic adsorbents are very expensive in production process. This review is mainly focused on removal of dye using low cost natural adsorbent materials. This review paper clearly brief about the treatment method for the removal of dye using low cost natural adsorbents.
