Abstract

Pollution from industrial effluents that is organic, inorganic, or dye coloured significantly disturbs the balance of the environment and human health. The textile industry is the leader among all other industries in the use of dyes to colour fibers, most of it flows into water sources that are challenging to be treated with traditional techniques. The treatment technique called biosorption which uses any biomass to absorb the contaminant from waste water. In this work, dried mass of Azolla pinnata, a flexible aquatic fern with strong biosorption capacity is used to remove Methylene Blue (MB), a frequently used cat-ionic dye, through the process of biosorption. In this case, we explored the biosorption of methylene blue (MB) onto Azolla pinnata. As a result, the main focus of this research was to identify inexpensive adsorbent for removal of MB dye in aqueous solution. For the elimination of MB dye, the plant Azolla pinnata is used as an affordable adsorbent. The purpose of the present research was to assess the removal of MB dye by the fern Azolla pinnata in aqueous solution. Investigations have been done into the batch technique's effective factors. Adsorption is examined to determine how well an adsorbent can remove MB dye. The capability of A. pinnata to adsorb MB was studied. It was found that the adsorbent could remove up to 81% of MB from the aqueous solution of 10 mg/L for the contact time of 4 hours.
