Activated Carbon Prepared From Various Plant Sources: A Review

Abstract

Plant resources are receiving increasing attention worldwide as a kind of renewable resources with low cost and widely available, the preparation of activated carbon from these materials at low cost from various natural raw materials has become a necessity now and in the future. This review discussed different methods for obtaining activated carbon from different plant materials using different activation methods and activation agents (chemical and physical). The results of the review showed that the types of activated carbon obtained have large surface area and greater adsorption capacity. The use of low-cost and widely available raw materials for the production of activated carbon is the main objective of this study such as (corn cob, rice straw, peanut shell, oil stones, and ficus leaves). It was found that chemical activation can develop both microporosity and surface area. The best raw material used is peanut shell, which can then be used in the field of environmental pollution (dyes, pesticides, heavy metal ions, phenolic compounds and other organic and inorganic pollutants). It was found that the adsorption process using activated carbon is a method that can be applied to remove various pollutants.
