MAIN DIRECTIONS OF USE OF WASTE OF PLANT RAW MATERIALS (PEANUT SHELL) AS ADSORBENTS (RE-VIEW)

Currently, one of the major and global problems is the treatment of wastewater from organic industrial waste, such as textile waste. The solution to this problem is the production of environmentally friendly adsorbents based on plant raw materials. The increasing use of natural resources, biomass recovery, and biomass waste in the past decade, has attracted the attention of an increasing number of scientists. Activated carbon (AC), used to remove organic micro-pollutants in the world's wastewater treatment plants, is typically produced from non-renewable resources such as peat, lignite, coal, anthracite, wood materials, waste from the paper industry, leather industry, and animal substances that must be transported over long distances. The use of local residual biomass as feedstock can be beneficial in terms of sustainability. The review is devoted to the analysis of publications in this area in recent years. The main areas of application of adsorbents based on peanut shells are considered. Examples of the implementation of the production of an adsorbent based on plant waste and their use for water purification from various chemicals are given, as well as the advantages of using a technology based on the adsorption of organic substances on activated carbon.
