Treatment of textile effluent by using Burflower tree (Neolamarckia cadamba) leaf powder: Batch biosorption study

Abstract

The textile industry is one of the leading causes of major environmental problems worldwide. The textile dye effluents hold diverse kinds of dyes along with other contaminants. Various environmental legislations have been formulated and obligate the textile industries to treat the effluents prior to discharge into water bodies. The present study aimed to evaluate the efficacy of removing two dyes, Congo red and Methylene blue, present in raw textile effluent by employing the powdered leaves of the Burflower (Neolamarckia cadamba) tree as adsorbent. The experiment was performed in a laboratory scale. The surface characterization of the adsorbent was carried out using Brunauer-Emmett-Teller (BET) surface area analysis, CHN elemental analyzer, FTIR and SEM-EDX analyses. The effluent was characterised before and after the biosorption process to check the efficiency of the process on the various parameters of the effluent. The values of the examined parameters were found to be decreased after the adsorption process. The removal percentages of the two dyes (Congo red = 76.35% and Methylene blue = 85.8%) using the adsorbent were also estimated by batch experiment studies. The findings of this study infer that the adsorbent as mentioned above, can be used to treat dye effluents.
