Evaluation of methyl red removal potential of adsorbents made from Leucaena leucocephala leaf and bark materials

Abstract

The aim of this study was the investigation of how adsorbents made from Leucaena leucocephala (L. Leu) leaf and bark materials were effective in treating wastewater containing methyl red dye (MeReD). The functional groups in the phytochemical elements from the bark and leaves of L.Leu offer active surface sites and enable the adsorption mechanism. The investigations were done in batch mode. Contact time, adsorbent dose concentration, temperature, pH, and initial MeReD concentration were all examined as significant parameters impacting the sorption process. The study found that significant MeReD removal efficiency was achieved after 90 min of contact time, pH 4.0 units, 1.2 gm/L adsorbent dose concentration, 100 ppm initial MeReD quantity, and 30 oC temperature. The developed adsorbents were applied to samples gathered from dye companies in Hyderabad and Guntur. The extraction of MeReD (81.2% to 90.0%) from untreated wastewater contaminated with MeReD using developed adsorbents was very efficient.
