Application of Taguchi Methodology in adsorption of Malachite Green dye using chemically enhanced Bambusa Tulda (Indian Timber Bamboo)

Abstract

The capacity of Bambusa Tulda (BT) with chemical improvements to remove Malachite Green (MG) from water bodies is the main topic of this research. These improvements were achieved by employing an idealised Taguchi L16 orthogonal array design. The pH, starting dye concentration, bioadsorbent dose, and contact duration were all elements considered during the treatment process. Each one was found to have an impact. According to the findings, pH, preliminary dye concentration, contact duration, and bio-adsorbent dose in that order were the major elements in the elimination of MG dye. The optimal specific nitrification rate (SNR) conditions were determined to be pH-3, an initial dye concentration of 100 mg/L, a bio-adsorbent dose of 0.20 g/100 mL, and a contact time of 90 minutes. Contact time and bio-adsorbent dose were shown to have an effect on the results, while pH was the most relevant factor overall. This was confirmed using analysis of variance (ANOVA). Adsorption occurred in a monolayer in the Langmuir isotherm model. The chemical may include hydroxyl and carboxyl groups, according to the Fourier transform infrared spectroscopy (FTIR) data. Scanning electron microscopy was used to examine the exterior morphology of the Bambusa Tulda. Malachite Green dye may be removed from wastewater using a bio-adsorbent made from chemically enhanced Bambusa Tulda.
